None of that stuff matters; none of it has a set release date. Diablo 3 could come out this year, and then they could fire some people and delay it until Holiday 2013.
You never know, look at all the crap with True Crime/Sleeping Dogs.
Speaking of blizzard, I am going to attend a midnight sale of Starcraft II Heart of the swarm, if there is one in Dublin, whenever they decide to release the game.
I think summer would be a good time to release it but I'm not sure if they will actually release it then since no date has been set sadly.
Who cares about anything else?
Because Mass Effect 3
It also gives any pro players plenty of time to prepare for the upcoming tournaments.
