why no mention of sandbox shooters like Halo Reach? 2010 doesn't only comprise of the CoDs of this world.
image is an obvious troll, but it should be renamed to Doom vs CoD.
believe it or not, but shooters have evolved. On one side of the spectrum you have the arcadey cinematic fun of the CoD games and then on the other side you have the 'sims' like ARMA II. And then everything in between like Bioshock and Halo and Half-Life.
I don't think that image proves anything. If you don't like playing shooters these days, I think that has more to do with your changing sensibilities as a gamer than anything to do with the game industry itself.
Look at Bioshock Infinite, if that doesn't excite you for the future of shooters, then I think there's no helping you.

More importantly even as in all things, its market driven. If people buy other types of shooters you get other types of shooters.
Borderlands, Stalker, Left 4 Dead, Vanquish, New Deus Ex, Uncharted, FarCry, Mirror's Edge, Brink, Hell, even Fallout 3 and New Vegas etc are all different kind of FPS games or 3rd person shooters. If people buy them, you will get more of that. If they don't you won't. Its pretty simple. Its no different than any other genre on the market.
Haters gonna hate in other words.
