As far as the next home consoles I think the launch years are: 2012 for Nintendo (as they have stated), 2015 for Mircosoft (because they want to milk more profit out of the 360 before taking a leap into their next console as well as getting costs lower for making the new console), and 2015 for Sony (so they have more time to recoup money lost this gen and get production costs down on their new console as well).

I am not really sure what kind of features I would want the next consoles to include that could convince me to upgrade. I guess the just really need a ton of exclusive games, a great controller (like the DS3), super fast loading times, stable 60 frames per second, and lower game prices. << (That sounds rather good actually :D )
