My predictions is:
Next-box --> late 2011.
Wii 2 --> late 2011 or 2012.
PS4 --> late 2011 or early 2012.
All 3 companies will try to release new consoles around the same time. SONY and Microsoft will want to prove their platforms are viable while Nintendo will not want to risk the competition recovering market share. The Wii will selling though until 2013/14.
