How long do you think we have to wait before we get a new Metroid?

[miz1q2w3e]

Metroid Prime: 2002/03
Metroid Prime2: 04/05
Metroid Prime3: 07/08
*Metroid Prime Trilogy: 09
Metroid Other M: 2010

Based on this, and the fact that I think they're gonna want to take a teeny break, I think it'll be another 3 years (it's 2011 now) until we get another Metroid
