With IBMs linux blade servers using IBM 970 AKA G5 aimed at headbutting with dual Xeon servers they do have a interest in having compilers that can wring out every bit of performance there is in the system

If that spill over into the BSD based OS X, I am just happy about that.
I do hope we see a very fast transition to good compiles for the G5. The G3-G4 transition was depressing as it took a two years for the G4 to get past the performance of a B&W G3/450 ( With the G4/733)
At least we will not experience the the 68k to PPC transition all over again were the good 601 CPU was bogged down both by endless emulation in the software and throttled by outdated hardware (slow SCSI, NUBUS etc).
Good news
