I don't really see the game changing part. I've been always able to get my software from DAZ really cheap, Hexagon was like 1,99$ IIRC. It's kind of a bold move to give the Pro version away for nothing, since a lot of people seem to have spent real money for it. 

Now, if you get half-baked and undocumented software for free you probably complain not quite as much as someone who paid real money for the software. 

 

About the WM-V4, we still have to see if this is a game changer. Don't get me wrong, it's an amazingly well done rig, a real benefit. But people will have to modify the existing clothes, and a part of it won't work right. It's not click-click-click-done, it takes a bit more work. A lot of people will use it, but I see no game changer here either. Not yet, at least.
