IBM's long-standing "Next-gen" "64-bit Commercial Core" mystery seems to be demystified finally. Indeed the longish-rumoured PowerPC A2 just seems to be that very core. When IBM released their POWER7 processor 1.5 weeks ago they concurrently (well, half an hour later actually ;-) unveiled their upcoming PowerPC A2 core and processors based on that core.
