I'm not exactly sure which part you have a concern with? The 4870 is noted as being close to the GTX260 but not outperforming per-say, and the slot is 4), noting that it is still behind my considerations for the 4870. I've agreed with everything you've mentioned here I believe, more or less.
I think you have your numbers muddled.
HD4850 comes close to, and iirc sometimes beats, the GTX260 but doesn't out perform it per-say. They are mostly on par iirc, but I've mostly ignored the HD4850 because...
HD4870 comes close to, and in some cases beats, the GTX28. Again, pretty much on a par.
Your ordering is correct when it comes to cost however, but still unless you need something the GTX260 or the GTX280 offer then it's an AMD no brainer.

[the HD2870x2] will also likely beat out the GTX280 in many cases
Anandtech ran a pre-view a few weeks back; the HD2870x2 beat the GTX280 in each of the 4 games tested. I suspect it will never score less than the GTX280, most likely only coming level in an OpenGL or Xfire unfriendly game as at that point its pegged back to a single HD2870.
Right now the only thing NV are king of is price, so in that regard, yes you proably have them in the correct order of least to most expensive (well, apart from the X2 card which might well be a little more than the NV offering but as it's not offically out yet).
I'll leave you with the following quotes taken from 2 of the pages you linked me to (the others didn't talk about the AMD cards at all); pretty much prove my HD4870 vs GTX280 point, for futher reading feel free to follow the link Gaiiden provided;

Wow! As the resolutions grew in the Crysis benchmarks, the HD 4870 overpowered the other cards in the testing, including NVIDIA's flagship GTX 280.

Again, the HD 4870 seems to do better at high resolutions, even beating out the GTX 280 at 1920x1200. [knights of the sea]
Quote:
Once again, the HD 4870 comes out near the top at the higher resolutions, just falling short by two frames at 1920. Awesome. [bioshock]

Even with high framerates, the HD 4870 was only slightly faster than the HD 4850 card in Call of Duty 4. The GTX 280 showed its muscle in this game across all resolutions.

The ATI-based HD 4870 averaged well in the higher resolutions, even trailing at the feet of the GTX 280. [World in Conflict: I dispute 'trailing' given a 38fps vs 34fps advantage to the GTX280]

The HD 4870 won every resolution in the Call of Juarez test.

The HD 4870 was holding on during the whole series of resoltuions until the end where it just could not keep up.[CoH:Op Fronts]
In all those tests no mention of the GTX260 at all. AMD shown to be on par or in a couple of cases beating the more expensive GTX260, with CoH:Op Fronts being the major loser for AMD by 36fps vs 49fps.
