I don't think it will slow down much this year. I think perhapse mid 2008 is when it will happen. There aren't many big title scheduled beyond God of War 2, but given the huge list of past games it will continue to hold on well. I think the 360 will pass it in monthly sales this holiday season, and the PS3 will do it sometime early next year. After that it will drop and by the end of 2008 it will clearly be a fourth place console. Though I expect Sony to keep producing them at least through 2009.
