How long until PS3 overtakes the 360 in total sales?

[Game Over!]

PS3 will overtake it end of 2009 beginning of 2010. I predict though that MS will release the next XB around 2010 or 2011 at the latest and completely abandon the 360 like they did with the XB.

 That would be very likely MS. They never cares about the consumers, but just money...
