Blizzard indeed pulls a blizzard by delaying until who knows when.
If I'm not mistaken, Blizzard North is all but dismantled (At least, the four who founded that division at least) because of dissatisfaction with Blizzard's master, Vivendi Universal. They were going to put Blizzard up for sale, Which the Blizzard North didn't take kindly to.They then retracted the sale, but since they didn't like their proverbial chain jerked, the founding 4 left to do their own thing. Before I go really off topic, expect Diablo 3 (if it surfaces within our lifetime or ever) to be have a different feel.
SC Ghost should light up 2005 (Or make for a good launch title for the next batch of consoles..), there aren't any super-killer appz on the schedule. With the exception of Zelda and RE 4 of course...
They did say that all 3 versions would be identical, including some online support, but I'm not holding my breath.
