i agree that it would be doubtful as well... though not impossible, which means you can keep waiting if you want, but it is highly unlikely itll happen either way, amd still doesnt even have theirs out yet... so you can wait up to another year or more to see what comes out for AGP
although youre reluctant to hear... an example of interface limitations was given in a recent article on THG, the 8800s are bottlenecked by the AGP 8X (PCIe 8x) bandwidth http://www.tomshardware.com/2007/03/27/pci_express_scaling_analysis/ ...and yet to be released cards will most likely be relatively close to on par with that performance, if not faster... to make newer and more demanding DX10 games still playable
AGP can be compared to 33MHz PCI in this respect, we have now officially reached the point where AGP (much like 33MHz PCI was) is too slow to not bottleneck current GPUs... because unless they happen to come out with an AGP 16x slot, its not looking very bright either way
