You better believe it! It seems to be something he does for the launch of a new monthly shougakukan magazine (Shonen Gessan, if I've gotten the name correctly). I've never heard of Adachi doing monthlies before?
What do you think? Rather a continuation of Cross Game or a new series? I want both, but... And the forum where I found this posted had it stated that it was a continuation of Touch. Yeah. Right.
EDIT: You know, with Adachi winning an award, Cross Game soon starting a third part AND getting an anime and the this, Adachi really seems to have gotten his hands full. The only question I've got is... How did this happen all at once?
