the action isn't going to go anywhere, since as much as people love to say otherwise, it's been core to the RE games forever. you might be low on ammo for the first 15 minutes, and then you go guns blazing. about the only exceptions to this i can think of are the first one, REmake, and i think one of the dreamcast games. i do agree that they've lost any sense of atmosphere though.
with that said, i'm actually fine with the actual game mechanics of 6 staying around, because if you experiment with it, it's actually a VERY damn fine action game, and if i'm going to be shooting zombies, i'd prefer it be actually fun instead of camera angles. i do think they need to do something about how hollywood style the action is though, because it really is just a shooting gallery at this point. i don't care if they keep this style of gameplay, hell, if they can make the co op more than just "hurr both of you press enter to open door" then i'm totally okay with that too, but they need to do something. maybe a limit on how much ammo you can carry, shots matter more, etc. i'd say lower ammo count, but again, that's not been a problem for the majority of these games.
as for E3, it's pretty normal around this time of year, but this is also a very big year. nintendo has to do something, since even though they're doing better than people believe, all the negative press around them is going to take effect eventually. microsoft also needs to do something to catch up to sony, who is somehow breaking sales records despite having absolutely nothing to play on the system. maybe they'll take a page out of sony's book and do nothing but talk about sales for 6 months and that'll make xbones fly off the shelves.
