I'm sure that this move is directed towards the advancements of Intel and their quest to make their own graphics solutions inhouse. And I'm also sure that some where deep down in there, this is a move to also make cell seem overly expensive and unneccesary somewhere down the line.
Since Intel hopes to make its own grafix solutions, IBM & Sony hope for cell to be its own grafix solution, and AMD buys ATi* for grafix solutions..... where does this leave Nvidia?
*Doesn't Apple use ATi for their grafix solutions too?
