Is Jasper the Xbox 360 Red Rings of Death antidote?

Microsoft has kept it fairly quiet, no press releases or launch trumpeting, but it now looks like the Xbox 360 has been upgraded with the new Jasper motherboard. The new Xbox 360 has been spotted in the wild by the eagle eyed Xbox Scene chaps and as a result we now know that it has a 65nm GPU which, Microsoft is likely to be down on both knees praying, will mean less of those Red Rings of Death problems which have haunted owners of the console, myself included.
