The 360 is already nearing 40, so I think they wil lsell 12 this year, and about 10-12 the next, so I think 70 is in the cards, or very close to it. Considering that most people would have laughed at 40-50 BEFORE this generation started, it is a massive accomplishment for M$. I think the next generation consoles are going to be delayed a year or two anyway.
