MSFT's stock is going nowhere.
Sony is crazy about thinking people actually spending like $600 on the PS3.
Nintendo's market share is lower with every generation of console, although I think they have the best approach with the new generation (360, ps3, wii).
Personally, I wouldn't buy any of their stocks. Look for a good company who's stocks might actually go up more than like $1 in the coming year.
P.S. this would be better if the OT forum.
