This year is destined to be massive. Currently scheduled for release? Uncharted 3, Elder Scrolls V, Dead Space 2, Batman: Arkham City, The Legend of Zelda: Skyward Sword, Pokémon Black / White, Gears of War 3, Portal 2, LA Noire, Mass Effect 3, Dragon Age II, Bulletstorm, Deus Ex... and that's just the smallest, shortest of samples.
But what about 2012, 2013 and 2014? If those years have any chance of competing with the excitement of this year, people are going to need more than a bunch of amazing new games in 2011. They're also going to need a bunch of exciting new announcements.
