Sounds like Take Two isn't giving our GTA V's new-gen/PC release date even at today's GameStop expo. What in the world are they waiting for?
That said, it sounds like they did show some old-gen/new-gen comparison visuals (footage) that is impressive. Haven't seen it myself.
A guy I know who is there says there'll be new radio stations, vehicles, weapons, wildlife, rampages & photography. I can't confirm 1st-hand
Needless to say that I've been asking Rockstar about a release date. They've been mum.
I guess some of this is coming from a trailer that was shown. Again, I can't confirm directly; please allow for some game-of-telephone here
