risc (reduced instruction set computing) meaning less code for the same result. this is the powerpc architecture like the g5 mac. very good for emulation so dont be surprised if the xbox2 will run xbox games!
cisc (complex instruction set computing) meaning more code for the same result. this is the x86 based cpu like intel and amd. not ideal for emulation because it has too much overhead.
Xbox developers have used Macs for a while. If anyone watched the Halo 2 promo trailer where they interviewed some of the guys who work at Bungie, you can see Macs in the background. One guy was even sitting directly in front of one.
I'm no expert but I can't see any logical reason why one would suggest the other. OTOH isn't it kinda weird that a Microsoft product would use a MAC as the development system. I know the Xbox 2 is using an IBM chip but I'd assumed it was going to be something totally new. I guess it's more like the PowerPC chip in the MAC than I thought. <shrug> if the Xbox 2 game developers are willing to let Mac people convert their games for next to nothing then maybe there will be more Mac games but as it is most Xbox games don't make it to the PC because the market isn't there, I don't see that it would be much different for the MAC. Do MAC owners typically have a joypad? I really don't know.
I know the hardware is Mac, but is the OS the dev kit runs on OS X? Also, since the development kit for XBox 2 runs on the Mac, I'm wondering if this means that more games will be released for the Mac. Anyone have any idea?
