When they say 3-d they just mean using a 3-d engine while keeping the original 3rd person perspective. The only reason they're going to do that is to make the animation and equipment changes easier. (In the old engine they had to hand draw every animation for every type of armor and gun combination).

I also heard that you'll have the choice of playing turn based or real time.

Of course its all rumors. :/
