Bertrand Serlet said something about compression in the keynote. Also note that the largest part of application size is not in binary, but in resources (images, nibs, etc.) Edit: also, all major apps are compiled with 64-bit support (and should run on 32-bit systems), thus it's minus ppc, but plus x86_64, which has a larger code size.
