People need to look at the pricing/chart. There was no card to fill the gap between 5770 and 5850. So they split Cypress performance into two new GPUs... Cayman for the > $250 range, and Barts for $150-250. Juniper is now < $150 and will not be renamed

Sounds like a good market plan, and 6800 was kind of necessary as a name since a 6700 would kill the 5700 sales, unless they wanted to rebrand the 5700
How do you figure?

5870 didn't replace 5850. Why would 5890 replace 5870? It really is a more fitting name as the performance increase is likely to be similar to 4870--->4890 than 4870---->5870.
