I think the built in HD-DVD version makes sense. It was hinted to in many ways, and really its the reason Microsoft got in the gaming business. They want to stop the PS3 and Blu-ray so they can take over the living room. They will never make enough off the 360 alone to justify being in the games business. There was clearly a bigger picture to it all, and they just lost.
So I think its possible the built in HD-DVD version was possible, with new more reliable hardware, HDMI, bigger HDD.
That got shot down, so they are slowly trying to cover it up as a supply issue. Really, how else does it make sense to completely stop shipments in the first two months of the year? If they really did this just for RROD its stupid, because they just game the US,UK, and Australia to the PS3.
