I think that no new consoles from sony and microsoft are going to be released anytime soon, because:
- Move and Natal will launch this year (They will definitely prolongue the consoles life)
- Developers are beginning to become more efficient with HD consoles, Higher Tech engines in these economic times will result in higher costs that third parties will surely want to avoid.
- Console manufactures began profiting from consoles (360), or finally began to profit from consoles (PS3)
- Big budget games will take forever to be made (FF, MGS comes to mind, FF XIII took 4 years !!!!)
Only Nintendo will launch a new console soon, and by a new console i mean an enhanced Wii
