I would really love for that to happen, renz. AMD charging $600 USD when they actually deserve it, I would have no complaints with that at all, but the problem is what they have showed and the current rumor mile is, that won't happen. Polaris won't leap over the improved Hawaii (Fiji) used in the Fury siblings, at least, not with *very* drastic changes to GCN (IMO, that is). They could do for the next generation (Vega?), but I don't think they can with Polaris, given current available information.
That is why their best bet would be to pull another 4K series "win". Engaging in a price war is better than selling no cards at all. It's like saying, they are better off with the position they had when the HD4K series came out than the HD2K and HD3K series before it. And the side benefit of actually going into a price war, is they will get some brand recognition from it.
In any case, let's see if they release something additional. Maybe we will know where the new cards performance will land.
Cheers!
