Did you just read my last post in that other thread?
I shall repeat my guesses anyway.
PSP - December 08/January 09
GBA - Fiscal Q1 2010

GB depends really, if you are counting GB and GBC together, then it has to get to 118 million,... That's a bit too far away for me to predict, maybe late 2011.
DS I doubt it will pass unless a sequel handheld is introduced before 2010.
