I'm seeing people talking about morphs and empty channels, so before everyone gets carried away (I know it's a bit late for some of you), you should know that morphs will be where one of the biggest differences between the two versions will be. Poser INJ/REM files are useless for the Tri-Ax version of Dawn, as you just can't Inject into them, I found this out the hard way when I converted Aiko 3 to Tri-Ax. DS4 also has the problem of not being able to create any INJ/REM files, so there is no easy way of getting any done in DS into Poser, as a result all morphs that get released for Dawn will have to be a joint effort between Poser & DS users.
