First: it has to be out: Second: It will run on AMD, sooner or later. We got everything to work on AMD yet. If Intel doesn't plan various processor instructions like SSE5 or something like this.

This instruction set war is a real problem: Intel now has as newest command sets SSSE3, AMD in the Phenom CPUs SSE4 or SSE4a. Interesting is the story of AMD64 and SSE3: AMD invented the 64bit instruction set AMD64 (on Intel EM64T). Intel wanted to use it, so AMD got as exchange the SSE3 instruction set. These instruction set battles should be regulated externally. If a software uses an instruction set which the other processor manufacturer has not it won't work on this processor, and so it would be a market distortion. It's a bit as using umlauts depending on a language: on an English keyboard you can't type äöü ÄÖÜ directly. You have to 'emulate' these keys using the character table or a ASCII-input.

Another question is if new instruction were used. A software producer must think over to use SSE4 because the most processors which are actually used now in a lot of computers don't have them. Programming a game using an instruction set (f.e. in a game) which have maybe only 3% of the computer users this would be not very intelligent if you want to make money with the software. Apple don't has to care about not some instruction set problems, like missing SSE3. We needed an SSE3 emulator for this on some computers. But if they now plan to use newer instruction sets are using newer instruction sets (I heared something that Aperture should be using SSE4) they won't work on the earlier Macbooks. By the way, Aperture is working on AMD, unpatched, so it seems they didn't use new instruction sets.
