I'm really confused by what has just been released? It's a bundle of Cyborg Version 4 and Cyborg Model 4. Right?
The "What's Included" says that it contains Model 4 and Version 4, so I'm guessing it's just a bundle with nothing new added. The bundle is actually listed as a 'New release', so perhaps both Cyborgs were among the top sellers and either DAZ or DZFire decided to bundle them up together and add them to the sale as a single item.
If that really represents the list of top-selling items, there are some definite surprises in there. Many of them are more or less obvious: Stephanie 5 Pro Bundle, Victoria and Michael Combo, Michael 5 Pro, Cyborgs, sure. I can see those being in the best seller list. Others are less obvious. Not that they're not all excellent products, of course, but, there are definitely some unexpected items in there.
