Yeah, maybe.
Even though everyone seems to think this will be the longest generation, it seems like it's going to be the shortest. Last generation we seemed to get two iterations of an IP (very generally speaking). Two GTs, two Metal Gears, two Final Fantasy's, two God of War's, two Halo's etc.
This generation, with the insane development times, it seems impossible that this could happen again. When GT5 is out, it seems like they'll have to start GT6 for PS4 because the development times will be even longer.
If we've not going to get these additional iterations, this generation is going to suck balls in about two years.
(sorry for the rant, it was on my mind)
