I am willing to bet that the PS3 will outsell the 360 by Year's end..

[Reasonable]

If you mean the PS3 will sell more than 360 WW for the rest of the year, you might have a chance, if you mean the PS3 will overtake LTD sales WW by the end of the year that seems a lot less likely.

And I do mean a lot less. The PS3 would need to fly of the shelves faster than they can make them to push through more than 8M in additional sales over 360 by 31st December.
