Id be cautious as to price drops, large ones anyways.
We dont know the full potential of nVidias card, as in, is it just a lil better or alot better than ATIs?
We also dont know the pricing to perf nVidias going to come in at.
My guess is, Fermi should outdo the 5870, but 2 things to consider here:
1 If it barely outpaces the 5870, but nVidia decides to use the Halo pricing in a large way, therell be no reason to see ATIs price drops
2 If nVidia decides its going to hold onto its previous high costs, and if Fermi does have a nive perf increase, they may take the high pricing , tho theyve said they wouldnt, it all depends until we see them on the shelves
So, in the end, dont expect ATI price drops, tho theyre certainly welcomed by us
