There are a number of languages that Scholastic is able to publish in, although at this time all we have confirmed is English. That doesn't mean it will stay that way, but it's too soon to know.
Shorm, at this point we aren't even sure that the MM and Chronicles books will be reprinted at all, with or without new covers. The confirmed release list right now covers #1-#6 (I believe). It's my assumption that Scholastic will gauge future releases on the popularity of the first half dozen.
