Even though that will probably be true, it's not a given.
Comparing the HD4870 X2 to the GTX295, the HD4870X2 is two HD4870's, while the GTX295 is not 2xGTX280's (or 285's, or w/e).
The GTX295 still beats the HD4870X2 (IIRC), but it isn't 2xtop end chips, unlike the ATI card, so it would be possible for the HD5870 X2 to beat the GT300 X2 by virtue of being top end vs mid-top end, although it's still not going to happen.
The point is that winning the single chip battle doesn't win them the dual chip battle necessarily, since it isn't always 2xtop single vs 2xtop single in dual card battles.
NV beating ATI in pure performance owuld be no surprise whatsoever to me and I expect many others as well, but I would expect the ATI chip to be close in performance, but likely quite a lot smaller in terms of the chip area, and thus cheaper to produce.
