>There is also interest in Shirley, the companion series to Emma, but the company has no announcements at this time.

>Oh, I asked about Emma 2 which recently started in Comic BEAM magazine. The manga is very new and runs monthly. CMX could not comment on the title at this moment but they did say Shirley is coming. More maids is more maids right!!
So one says no, one says yes, but the second one also seems to imply that it's only the one volume, not the second series "Shirley Madison". So who's wrong or right here?
If somebody could get a straighter answer out of them, that would be great. For now I guess we wait until they say something official.
Coy comments like that basically mean "We probably should pick that license up one of these days, but no need just yet."
