Judging by the last few Black Friday's/Cyber Monday's, you're more likely to see the mid-range cards have better deals and better availability due to the sheer fact that they are larger in quantity and are more attractive in pricing/performance.
If the GPU (or any item for that matter) fits your budget, and happens to be cheaper now, I would buy now instead of waiting for later. The longer you wait, the less time you have of actually playing your games. Besides, with the way things are going with TSMC and their 28nm manufacturing process, I wouldn't be surprised if people would have to wait until late summer in order to get their hands on a decent supply of new GPU's.
Agree 100%. I just bought an EVGA GTX 580 Classified 3GB. For over a month I was on every notify list and had to make sure I was by my PC when shipments were scheduled to arrive to get it. EVGA can't keep them in stock more than 15-20 minutes...if that. That card's not going on sale for a long time. I doubt you'll see any discount on GTX 580 3GB models other than maybe reference models.
In addition to the problems with TMSC's 28nm process which caused both AMD and NVida to push back release dates, there easily could be issues with the new GPU designs. Furthermore, at least for NVidia (and I think AMD) they are releasing in reverse order from normal - lower level & mobile GPUs first with high-end desktop GPUs last. Covert ash could very well be right about a summer 2012 relese for next gen, high-end desktop GPUs.
I also think that where you'll find deals will be cards like the GTX 550 & 560s (and AMD equivalent) along with lower VRAM models & reference models of the GTX 570 & 580.
