Doesn't really matter - ATI are now in a state of playing leap-frog with Nvidia, so we'll see cards from ATI that do similar things soon.
Actually, nVidia just leap-frogged ATI. :-) The Radeon 9700 Pro was considered the best card out there, but it now seems the nVidia FX might top it. Haven't seen any benchmarks yet but I have a strong feeling that ATI will be left in the dust.
But that's okay, even if they did make drivers for the AmigaOne, would any software take full advantage of it? Probably not. We just gotta get the ball rolling and not worry too much about the ultra-high end. Those cards cost over $500 anyway, so they won't become common until a year or so later.
