Well, the consoles need to actually make it to 1080p first, and then add some AA/AF. Personally, I hope that they use something a little beefier than a 5850 so they can apply the aforementioned AA/AF to 1080p, plus have a little room to grow over the console's lifetime.
I don't think many other companies have anything comparable either. nV has a great product in Tegra. However, I've heard Tegra 2 might not be a full SoC? Which IMO is getting away from what it should be if that is in fact the case.
