Yea, hopefully they should drop. There are some deals right now though if you cannot wait. Look on fatwallet and search "GTX 260". Currently, they have deals for around ~$200. But if you look at the older posts, there are some that are cheap going down to ~$160-170. There is a deal with a power supply, if you sold that total price for GTX 260 would be around ~170. I am also waiting for a deal and checking pretty much every hour. I am looking for EVGA branded GTX 260 only though....since other card manufacturers have a lot of problems (PNY). Happy deal searching .
FWIW, I just got a 4850 and if I had it to do over, I'd get a 260 and I'd have spent the same money if you count the fans I had to buy to cool the 4850.
right now the GTX260 is hard to beat value wise. But I look for nvidia to hold the prices up on the 216 shader core models until they move some of this stock.
