"Rewritting" isn't really accurate. I don't know about AW and Isolator, but for SAO, Kawahara can just take the web version text, re-read it and make some adjustments where he feels that they are needed.

And since when has Kawahara been working on a manga? Just because he's credited as the writer, I highly doubt that he actually writes it.

As for the Alternative, it's only good news if you can either read Japanese or Chinese, since I highly doubt that there is an English translation.
