Nice article. Short and sweet.
Diablo will go out for PS3 likely with an announcement shortly before the announcement for a PC Expansion. PS3 because Sony is a lot friendlier then Microsoft and their system is a lot better for developers that patch their games a lot. Microsoft offers 1 update to the game for free after which you have to cough up a lot of money for every consecutive patch, because of their servers. Sony uses a cloud so patching is no issue on the PS3.
Also Sony, Valve and Blizzard are some of the companies that are really working on making cross-platform play, meaning PC players will be able to play with PS3 gamers. That would be excellent for Diablo.
I'll be playing on my PC but a console version would be great for those that don't have decent computers. If it were to come out for consoles I'd also love to see cross-platform multiplayer. Assuming you'd have to connect to Battle.net anyway, I'd think this would be theoretically possible
Without cross-platform multiplayer, I'd probably end up buying it so I could play with my console buddies.
