Well it's actually 6 years and 8 months.

So that's june 2012 to outlast the PS2.

I hope Sony, just so I can ROFLOL on their 10 years plan.

Microsoft will be neck-and-neck with Nintendo, though my vision of things is changing a little. I now think that Nintendo will release in 2012, though whether early or late is unknown, since they have just enough to keep them well alive through another holiday season (after this one)

Sony is the only one that really has reason to wait (in that unlike Microsoft, they care about long-term profitability in their games division, so will want to hold off if there's no undue pressure to jump)

I think its in Nintendo's best interest to launch first.

However I used to say Nintendo's next console will launch in 2011. With the 3DS launching in spring 2011 I no longer believe a 2011 launch for the next Nintendo platform is plausable.

With Nintendo's sales waining and the Wii loosing market share I think its becoming more and more likely that Nintendo will kickstart the next gen in winter 2012. I think Nintendo's next system will be announced next year at E3 (Briefly) and a full unvieling at E3 2012.

Hears an interesting idea, I would put money on it. My own prediction. I think that Nintendo's next console is already 90% complete. I think Nintendo had planned on releasing the next system in 2011. I think Kinect and Move caught Nintendo off guard and that they have simply delayed their platform. My bet is that early dev kits are already in circulation within Nintendo. I'm 75% sure that Nintendo will have dev kits out to developers by GDC 2011.
