What? Look at how the DS has sold and know that it only recently passed 100m sold, and is an older platform than the PSP. Also note that the PSP's really only relevant in Japan, America just hasn't really been too interested in it.
65-70m seems like a reasonable prediction, and you can't call it anything other than a success. But it is not a DS sales monster, and I don't think PSP Go will do much to change this fact.
Bet between Slimbeast and Arius Dion about Wii sales 2009:
If the Wii sells less than 20 million in 2009 (as defined by VGC sales between week ending 3d Jan 2009 to week ending 4th Jan 2010) Slimebeast wins and get to control Arius Dion's sig for 1 month.
If the Wii sells more than 20 million in 2009 (as defined above) Arius Dion wins and gets to control Slimebeast's sig for 1 month.
