Look at it this way: ATi is offering, for the same price, a slightly faster card. What's wrong with that? Incremental progress has given us the 3.2GHz P4 and 3200+ Athlon (not to mention the GF->GF2->GF3->GF4 and 8500->9700), so I don't see why the R360, NV38, RV360, and NV36 are rip-offs.
If you have $400 to spend today, you're going to get more for your money than if you had it to spend last year or even last spring. That's progress, baby! It may not be a huge leap like from the GF3 to the 4600, or the 4600 to the 9700P, but those leaps really only happen with significantly revamped chips. Sure, the NV40 and R420 will be more exciting, but the XT ain't too shabby. Dynamic OCing should be interesting, too. Cat 3.8's are due within a week or so, so we'll see what that feature does for XT performance in Part II of Anand's article.
