the question is when.... and i highly doubt it. People have been saying that since the 64 came out. sure nintendo made some bad moves in their day (n-64 w cartriges and close to ZERO online games for the GC).
you gotta remember, nintendo doesnt only make consoles. Thier cash cow right now is the Handheld market. That SP is still goin strong, i havent seen the sales numbers yet, but ive seen more DS's than i have seen PSPs around.
