AGP 5xx parts were on a roadmap thingy. So if plans have not changed then yes. But one has to wonder given the physical length of the boards if there is still room for a bridge chip as the PCIe models seem as long as the 4xx bridged ones already and a native AGP high-end part would seem less likely (if not for that, anyway... but I wouldn't discount a volume AGP part). In any case, don't hold your breath. But then again, the previous delay must have been due at least in part to initial development of Rialto and the scuttlebutt is that ATI has already missed out on Yuletide OEM (read: PCIe) orders so mayhaps AGP upgrades will gain more focus. So yeah, I can definitively confirm maybe.
