1. Played it for 360
2. Not wii, but basically the same, just without downloadable content.
3. Spring 08 is the first time you'll be able to buy a guitar separately from the game.
4. No, I'd expect that in Guitar Hero 4 though. (Which as been announced)
Well, remember that the wii version has no downloadable content, but the 360/PS3 version has recently gotten tracks from the Foo Fighters and Velvet Revolver. There will be more to follow I imagine but that is it for now.
actually i just found out that the guitars sold seperately should be released 1/28/08. that's what i read today, before today i found everywhere it said early 08. so i'm assuming the date i have is more accurate rather than the pervious post. =]
i was gonna buy an extra guitar yesterday but it was $80.00 so ill probably get it off ebay or sumthin. and yes there will be downloadble content for wii just not yet
