Reading other rumours I don't think the 5770 will be renamed to the 6770, I think the 6770 will have the same architectural changes the 6870 will enjoy on a smaller scale and will become the 6950 in x2 form, while the 6970x2 will be the full blown 6870 dual we'd be expecting from AMD.

I do think the 5770 might be tweaked and re-branded but as a much lower model.

Going back to this:

It's also possible to make with the switch from 5 to 4 to make a smaller part with a similar number of shaders and higher clocks that would give impressive performance on the right benchmarks. If you only picked benchmarks that were heavily biased to complex shaders you'd get the results we've seen posted, however on benchmarks with simple shader bias there would be next to no change at all.

The point that is making me think this was is the rumour that AMD is launching the 6770 first and not the 6870, not even nvidia would launch a new generation of GPU's with a re-branded unit. I guess we'll find out if AMD starts dumping the price on the 5770 or leaves the price high in order to protect stock of the silicon they plan to re-brand.
