This thread here discusses the expressions issue. See if you are following the right procedure.

This one was listed in the description of the product, very convenient.

and this other was aswell, though this one is themed instead of a replica

MetaHuman won't make DAZ obsolete, because it will be cloud based and this means no control and no modifying of those barbie/ken characters and they will all be some kind of "lookalikes", a problem all "ingame character creation systems" do have. They seem to have just one skin texture and one normal map (for aging effect), where you can set the strength etc.

As for the cloud: If they decide to take the application down, it will be instantly forgotten as if it never existed.

Another point is the horrendously bad performance (like with every object/mesh using materials with an extensive blueprint setup) which makes it impossible to use it in open world environments. With UE5 you will still have to reduce polycounts for skeletal meshes (and foliage). Only static meshes

won't need a LOD system anymore. That's the reason why they have shown  only some dead dessert environment in their promo, but no huge forests.

The hair technology you see in the examples is something UE4 specific and probably can be used with any character, no matter if DAZ, MakeHuman etc.

As for those nice skins: This is nothing special, just some good PBR textures (with some additional maps, not just diffuse,specular and normal) with an advanced shading/blending algorithm. You only need some good textures and can freely copy the blueprint node setup and voila you have a similar skin quality.

I've heard somewhere that DAZ uses this PBR technology to a more advanced degree as well with the new Victoria 8.1?

And I'm sure that MetaHuman won't have the full range of morphs, clothing options, hairstyles, bone driven morph targets like DAZ has and it probably won't have even full human bodies. Hell, the standard UE4 version doesn't even have Dual Quaternion skinning, so the characters either will deform badly or they will always have some clothing on in order to hide the bad deformations.

To conclude I can say it will be very limited and not usable outside of UE, so any modding on a broader scale will be impossible, maybe with the exception of some minor adjustments.

BUT, I already had V1 at that time, so it must have been earlier than that. I already had M1 as well.

Morph Loader and D-Form Plugin from 2006-04-22. They are the oldest products in the loit. Before that were three orders, one for Studio 2.3.3 and another for Aiko 3.0 Base and Michael 3.0 base and the third for Victoria 3.0 base. There are 1321 orders on the list. I think I would rather not have known that.

Coud be worse I have  4145 

Yes, that would be worse. Much worse. Very much worse.  Probably almost the worsest. 

Actually it's worse as there are older orders that aren't listed

Like a few others, my first was for the original Victoria figure and probably a hardo and some clothes. Daz isn't letting me look at the order now for some reason, but I assume it was probably a CD like some of the others suggested. That order was placed in March of 2001.

This was for a contest that the rules stated you had to use a dragon but the dragon itself couldn't be visiable 

I haven't looked that far back at my first orders in a long time. The first ones were free in 2005; they are listed as DAZStudio_2.3.3.146 (was that really the version number that was out then?), Victoria 3.0 Base and Michael 3.0 Base. The first paid order was for Castle, which is a brown castle with a red roof. I got the M3 and V3 morphs for $29.95 each soon after that.

Someone started a threadin Commons on what was your first purchase here. Looked it up and in a few months it will be 20 years ago: May 19, 2001 Victoria 2 SKU 83. How time flies!

My first purchase was on May 19, 2001 for Victoria 2 SKU 83

My oldest purchase came on a CD : Victoria (aka Millennium Woman), Yup, I got it in the mail 

IIRC, the first Zygote (pre-Daz3D) product I ever bought was the Buck and a few other things. Came on a CD that I got in the mail. Millie (Vicky 1) wasn't even a twinkle in someone's eye quite yet ;) We were all still using Posette and Dork at the time :P

As I said. Sacrifice your firstborn. Roll up your trouser leg and dance 9 times anticlockwise around a burning effigy of Victoria 8.1. It's bound to work fine... I mean, it's not like the wording could be even slightly misleading...

The oldest showing is Staff Pack 2001-12-30 https://www.daz3d.com/staff-pack

However I have older items such as textures for Posette and Dork (aka poser male), Victoria and Michael that were purchased when DAZ was known as Zygote that don't show up in my product library

"СyberV4" a bodysuit for V4 and you want your G8F to wear it, did I get that right?

1) Free way, usually works but not always:
Load a Genesis figure (Genesis, not Genesis 8!). Autofit your bodysuit to the Genesis figure. Load your G8F. Right-click in your Scene tab on the bodysuit, click Fit to..., select your G8F. When the autofit menu appears, select Genesis and Full Body.

2) Paid: https://www.daz3d.com/sy-victoria-4-and-michael-4-clones-for-genesis-8

3) Paid: https://www.daz3d.com/rssy-clothing-converter-from-victoria-4-to-genesis-8-female

Okay, that's worked ! (And yes, I put it wrong, I want to use the CyberV4 model as a "skeleton" for genesis 8, because it should be under the genesis 8 model!)
But I have another question about the transparent plastic shader (on the example image), it's definitely a texture with a opacity layer. 
I made a similar one using three textures (roughness, height, and normalmap).

But here, too, most likely a specially made set of shaders/textures for iray, I can't find it.

UPD : When I apply CyberV4 to genesis 8, some parts of cV4 still stick out, and I just reduce the cyberV4 model itself so that they are not visible but all that scale is breaking mesh parts :(
