This announcement fits with the earlier rumour that Nvidia planned to add an x86 decoder to a modified ARM core:

I'm not sure they can get as power- or area-efficient as AMD's Ontario (or future shrinks) while reaching that performance level though. Even a modified Cortex A-15 would have less CPU performance, and the GPU is Geforce 6/7 class versus an Evergreen based Ontario derivative.
