According to Tiamat (via), Yen Press is going to re-issue Azumanga Daioh. The interview was dated before April 1.

The ADV release is the only translated manga that I have, so I'm not likely to buy the reprint. But I'm wondering how successful it's going to be, if the paper is going to be any better (the difference between the quality of the Japanese version and ADV's print was quite pronounced) and most especially if it's going to be re-translated.
