I think x64 WAS Itanium. x86-64 is the beast we are dealing with today. In that world maybe everyone goes to PowerPc? The move from 32bit G4 to 64bit G5 cpu wasn't a big deal since the PPC had 64bit variations back in 1997 with the 620 (though apple never used it)

Everyone would go where Windows would go, as far as I remember PowerPC Windows NT did not got much love.

  Yeah, that was kind of tongue-in-cheek. Apple knows when to leave a cpu architecture. They've done it 3 times already (M68k->PPC->x86->ARM) Though I think we're getting now to the point that we would have gotten to then. AMD bought x86 another 15 years of life.

Itanium was IA-64.

  you're right. I guess X64 and X86-64 are synonyms, more or less?

    Yes, x64, X86-64 and amd64 refer basically to the same.
