i wonder what they'll do on the feature side of things? (eg some new hd decoder, dx11.1 etc.)

Again, we are talking about new tech but nothing to test them I m guessing my two HD4890s are wasted even today, thats my feeling anyway.
personaly I think I ll get a HD5870 than leave it till the HD7k (unless NV gets their finger out)
Performance takes transistors, architecture changes account for VERY little performance difference, its all about more transistors, Fermi is HUGE, theres exactly no where at all for them to go in terms of a continuation of Fermi, which would require more shaders, more transistors and more size. It can't make the current one at a profit, one half as big again would basically be unmakeable, remember the current Fermi can't release a single fully enabled 512shader part because yields are so bad, no way in hell they could make a 768shader one.
There will not be a new "fermi" until 28nm, there "could" be a new Nvidia architecture on 40nm, they need something FAR more compact with much more performance per transistor used, and really no one can see that happening.
As for a refresh, where does it say refresh exactly, 6xxx series, not a 5970/5990, its likely to be bigger, but not massively better.
Your two 4890's have plenty of life in them yet. They out perform a 295 in quite a lot of titles.
I would but a few things, power, heat...some games hate crossfire. they are my only problems
heres the thing, so does the HD5870 and with being a lot cooler and needing less power.
Why do people care about tessellation?
You can honestly say you can see the difference at game speeds and not just staring at screenshots?
There's more to video cards then just out right performance just look at ‘eyefinity’ for example that has uses and appeal beyond the traditional PC Gaming crowd. So the next generation of video cards may not bring the huge leaps in performance that we’ve enjoyed in the recent past but they could bring newer and exciting technical developments
if 6870 is not equal or very close to 5970 performance then its not really worth of making them in it ?
