Sadly, hardcore RPG elements will likely never return to those game series. They've been neutered to appeal to the masses.
In any case, to answer the original question... As mentioned above by others, I too have a giant stack of previously released games to get through, so there's really no need to wait in anticipation for new titles.
I'm in for Mass Effect 3, Assassin's Creed III (set during the Revolutionary War!), Bioshock Infinite, and Grand Theft Auto 5. I still need to finish Uncharted 3 (half-way done), Killzone 3, and Arkham City, though...
I'm cautiously waiting for Birds of Steel. I've been burned twice by Gaijin now with bug ridden games and promised patches that never arrived (Birds of Prey, Apache: Air Assault), and a lot of finger pointing. This will *not* be a release day purchase -- maybe a rental first. If it still has a Texas-sized flight stick dead zone, I'll have to pass, no matter how pretty it is.
