Quickly?
Ati's newest offering today is the 9800XT, which is essentially an overclocked 9700 PRO... you know, the chip they launched about 2 years ago?
I don't think it's moving that fast at all. Both chip companies (Ati & Nvidia) have said they won't be releasing new architectures every year, from now on it'll be every 2 years or so.
All of the new products we see between the 2 year marks are modified versions of old products. (9600 is a value version of the 9700, 9000/9200 are value versions of the 8500, etc.)
