Well, that's certainly not going to tamp down on the Dark Sun speculation.
I don't see how them saying that Thri-Kreen are mostly associated with Athas, and that they were a playable race in previous editions translates to a Dark Sun being in the works. Not to say that it isn't as it may very well be but to me those comments were just a reference to the Thri-Kreens history in the game. Myself, I'm not reading too much into it, but just my opinion.
