If these boys are air cooled I'm happy... cuz it brings us closer to what we all really want.
If they can air cool a 2.7GHz chip... I have to believe they can easily air cool a 1.6GHz chip.
Maybe even with a 1/2" thick heatsink.
Maybe someone has already covered this, but the 2.7 ghz PMs are almost certainly water-cooled. Thinksecret has indicated that these come with only 512K L2 cache, which mean they're the same 970fxs as in the last iteration. From the look of things, all the specs (including the AGP8x, PCI-X, etc.) are the same except for the modest increase in CPU and bus speed.
As others have noted, the 2.3s are most likely the upper limit of what they can air-cool. The Xserves top out at 2.3 ghz probably for the same reason.
On a pessimistic note, we probably won't see another update until MWSF 2006, which is 8+ months away. IBM must be having a bitch of a time churning out 90nm CPUs, still.
While the PMs are still generally competitive with what the x86 world has to offer, the development of the G5s have been truly disappointing, given the promises originally made. Apple-IBM were expecting about 50% increase in processor speed every year. Instead, we're on something like 16% increase per year, which is quite sad. MOTO, even with all their struggles, still managed to eke out 15-20% increases every
6 months. So IBM-Apple's current struggles are unprecedented, just to put things into perspective.
