I think this is not a bad deal for WoW players:
Pay a year subscription for WoW and get a copy of Diablo 3 as well.
Digital download are these highly compressed as if D3 is 10-13 gigs thats a big dl for us, I don't know what the size will be but it would be big.

AoC the mmo for me atm so son paying WoW subs, tho I will be going back when the expansions out just to have a nosey.
This is the rumor going round.
Wow will have one more expansion after this one, lvl Cap will hit 100. Then wow will go F2P. Blizzard will being out Warcraft 4 after this and a new mmo 'Titans?' after that.
