I hope AMD doesn't make the mistake of getting rid of ATI's high-end chips. Maybe we can all sign a petition, "Save ATI Graphics!".
Back in 2000 when ATI bought ArtX team to design next generation GPU's because ATI had no choice in order to survive; they (ATI) spend all their money on R300 chip (Radeon 9700). If R300 were failure then ATI would be out of business, but nobody suspected even ATI themselves didn't realize how R300 was very successful chip that made ATI live even now.
And you think ATI went down so easily without a fight to survive/live and sold to slavery for/to AMD. I don't think so - they ATI probably had aggrement of some kind with AMD so they (ATI people red color now green color) continue make high end chips.
