Intel and x64 Question

My understanding that XCode generates i386 code, instead of EM64T/x64
IMHO 86x64 is way to go, with all new CPUs, at least due to larger register pool.
Does it mean we are going to go through "second transition", 32 bit to 64 bit for Intel with XCode? How will it work? Will we have 3 binaries one for PPC, one for i386, one for x64?
BTW, while your are at it, please drop Microsoft calling convention for SSE2 on x64, where they save half of SSE2 registers on every function call.
