Virtual PC not ready for the G5

Perhaps you've read on some sites the testimonies of G5 users complaining Virtual PC 6 doesn't function on their new toy. Asked by a reader from MacOSRumors, Microsoft explains why :

Virtual PC for Mac version 6.1 is based on a PowerPC G3 and G4 functionality named 'pseudo little-endian mode', that boosts performances while emulating a Pentium. The current Virtual PC version needs this functionality. But as the G5 doesn't support it, many code portions will have to be rewritten and tested with great care so that everything runs perfectly well on this new CPU.

Microsoft is thus not ready yet to commercialize a Virtual PC version that would work on G5s. [Now that we know RealPC is abandoned...]
