Expecting that one core will have a defect and can be disabled is a too long shot IMHO, usually a defect is more likely to occur in the big areas like caches that cannot be easily be deactivated. My take on this is that 15 is probably just the number of cores that'll fit on the DIE.
A case where a 64-bit ALU is of an advantage is everywhere where you have to deal with a lot of throughput, for example: compression algorithms, image processing where you need a lot of copying to and from ram and so on...

maybe they will finally also remove those texturing units from the Phi

I really don't get it, isn't looking for prior art the main job of the patent office before granting a patent?
