Actually 80M, which someone already mentioned on the first page, could be pretty realistic in a not-good-not-bad case.
I'd like to know why 80M is not good... Come on, the PS2 is at what now? 120-130 million more or less? Even considering PS2 didn't stop selling yet, how is 60-70% of PS2 sales not good? In fact I'd say it's too good to be true for a platform which is much less successful than the PS2.
