Anybody know if AMD/ATI have any history of releasing their high end cards way after (as in like 6 months) their mid range ones?

Hmmm, I just came back to the thread and it seems it's the second time that theory is proposed, but let's not forget the argument SA also proposes which is that Nvidia would have a more difficult time with leakage since their shaders run at twice the speed of the the core, so that could mean that AMD is able to release all their cards on the 28nm process that is ready right now.

They could however release some revisions six months after with some revised clockspeeds. They have launched many High-end cards in the past that superseeded their prior high-end, and all within the same GPU series. I'm thinking for example of the X1800 -> X1900, and even with those they released a lot of variants. X1900XT, X1900XTX, X1950Pro, X1950XT.

I don't recall if AMD has released the mid-range first many times, or with a six month period in between, which is what you are asking, but I do remember the release of the Barts GPU (HD6850 /HD6970) last year, so everything is possible. Even Intel started their 32nm production with Dual Cores (Core i3 and Dual Core i5's), so that is surely a possibility.

Maybe they'll do a refresh of current gpus, like with the 4770, which was just a 4850 with a 45nm die.

No, the HD4770 was not a 4850 with a 45nm die.

First, there were no 45nm dies for either AMD or NVidia GPU's. They are 40nm.

Second, the 4770 was not a die shrink of a 4850. The performance was more or less the same, but they achieved it in a different manner.

The HD4770 has 640 shaders running at 750Mhz versus 800 at 625Mhz for the HD4850, but uses GDDR5 memory instead of the GDDR3 for the HD4850, but uses a 128-bit memory interface, versus the 256bit memory interface for the HD4850.

For a comparison table, look here.

This. It seems as though neither company wants my money. : (
