We can't help but wonder if this is the nature of things to come. This is the first explicit moment of a trifecta release. Retail, digital distribution (Steam) and subscription service distribution (GameTap). That's just for PC. The PS2 and PSP editions come in their standard box at retail format. We still find it strange that the game still hasn't been announced for the Xbox 360. If it gets announced for XBLA, that's it, we'll have officially entered a new era of game distribution.
