apparently there was discussion about V4 at the artzone a few weeks ago from the featured Chat, speakers Dan Farr and Chris Creek. They spoke about a few of the new features that V4 will entail. I wasn't at the featured chat, so I wouldn't know what V4 new features will be, but I wouldn't be too surprised if many are pleased by the new upgrade designs to it.

I don't think there will be much discussion about it either till "it's" arrival. No pun intended considering she can turn into Michael in V3. LOL!  Just a lot of speculation or guessing or hoping what the new features will be.
