I would indeed be surprised if you can still reasonably get cpu's at this point with Apple ditching them.
Apple has ditched 68k, you can´t get 68k-variant-cpus anymore? :-)
Freescale had already shifted focus to the embedded market. G5s might get hard to get but the G4s ain´t a problem.
Though I wonder about the point of a 7448-based peg2,5, why not just make a cpu-card for the existing design and skip forward to the 8641D?
MPC8641D will be its most powerful chip yet, with dual e600 cores each delivering "greater than 1.5GHz performance." The chip will also integrate two 1MB L2 caches, dual AltiVec vector processing engines, a high-bandwidth integrated MPX bus (inter-core bus) capable of clock speeds up to 667MHz, a dual memory controller supporting DDR and DDR2, a RapidIO serial fabric interface (useful in Linux/AdvancedTCA systems), and four 10/100/1000 Ethernet MACs with protocol accelerators of various kinds.
This processor integrates two e600 PowerPC cores, two memory controllers, Ethernet controllers, a RapidIO™ fabric interface, a PCI Express I/O interface, and a high performance MPX bus that scales to 667 MHz. It's one powerful processor, but it doesn't break the power budget starting at 15 Watts.
Easier to make a small high performance board with that I think. :-)
But 2x1,5+Ghz isn´t 3Ghz and Steve promised 3Ghz.
Too bad Steve cant get 3ghz lowpower laptops from Intel..... :-P
