If the FW Candace page was genuine, it looks like Gen2/V6 are a DSON style product, which keeps compatibility with the Poser 9 family as well as Poser 10 via the DSON mechanism.
This in turn would imply DUF figure files rather than CR2.
(Pure Speculation/Educated Guess) To make Gen2/V6 Poser 10 native (e.g. without DSON), it would likely require abandoning some Daz Studio technologies to a compromise on common set of technologies between SM/DAZ3D. Most of the major feature needs for Gen1 are in Poser 10, but I think there a still some loose ends (including differences in how morph following/autofitting/geometry welding is implemented) that would need to be addressed. Not that it couldn’t be addressed in a Poser 10 service pack, but I get the impression that agreed upon route between DAZ and SM is DSON.
There was a recent discussion in the Poser Forum where the “official word” (DAZ’s, not mine) was to use DSON with Poser 10/Pro 2014. I’d be very surprised to see such a reversal of technical so quickly.
