A disaster for one company is business as usual for another. Genesi might have specific needs from their northbridge that Mai promiced but cannot deliver. (The RAM issue is still one that looms, for example) Genesi claimed that Mai did not work as advertised. This does not preclude the Mai from working, just not as-advertised. Where Mai is deficient may not appear in a desktop solution, for example. But remember, Genesi needs more out of their chipset vendor than *just* the Pegasos, as shown by the Eclipsis and STB deals. If Mai cannot deliver as-promised, then Genesi has wisely chosen a vendor which can deliver what was promised.
As for the G4 question, they never said it *couldn't* run a G4, but that Genesi was not going to deliver a G4 card for it. Commodore never made 68060 nor PowerPC cards for the Amiga either, yet I once owned a card with both of these processors on it at one time for my A1200. Also, as noted in the list, those owners of a Peg I can upgrade to a G4, by trading in their Peg I for a Peg II and paying the $200 for the G4 card (which was the original price anyways).
