Just from my understanding, Daz is not developing models to work primarily for Poser 5, but it should still work with it anyway. I think any model they release will work with Poser 4.03, as well as for their program that they are developing called, "Daz Studio". I don't really have any information about whether Victoria 2's clothing will work on 3, but hopefully they will. :) I hope this helps. :)
