I don't see the 360 coming in 3rd behind the PS3, LTD. The PS3 has a heck of a lot of ground to make up, and we're several years into this generation.
Also, I see a serious flaw in many of these kinds of predictions... they assume the competition (MS in this instance), will sit still and not counter with their own slim, etc. over time. These races are a moving target, and one turnaround by Sony or MS can't be extrapolated out to predict the final outcome.
But it is fun to read the predictions, so keep them coming.
