2010 - 2011 will see new portables from Sony and Nintendo I imagine.
I think it's too early to predict the home consoles lives but I can see PS3 Slim and Motion controller along with the X360 and Natal packages next year push those systems for a year or two at above a $200 price point which essentially means they have a long life left in them.
Wii will continue to sell and after nearly 3 years and still not one price cut.. I think it'll be at least another 3 before we see a successor.
