Well that site appears to be the online ones reporting that, but honestly if it's true, I'm ok with it.
We got closure on Asohka, we knew they weren't going to kill her off, so this was the only real option to wrap things up.
The last few episodes were easily the best of the whole series which at times dragged on with boring and pointless episodes.
This ending nicely caps it off and leaves a good legacy of entertainment. IMHO.
