The raw for Prince of Afterschool is up at Mangahelpers! There's a link to a partial translation as well. It's a super-cute gag manga that made me grin with glee. (OMG TEZUKA ♥) It sounds like it's serialized so there may be more later. I hope so!
The announcement about the new series in March was there as well, so that seems to be confirmed. :)
