I could imagine it going either way to be honest. On the one hand the idea is that it might work that he has at least the potential for an artwork update/upgrade if he so desires it for pintsize. In some cases we don't see updates because they are believed to be needed so much as the creator wants to make the change. It is possible that JJ might just want to alter pintsize due to some personal desire to do so or because he feels the time is right for it. That being said I kind of like the idea of them going through a little montage of bodies, and one off camera one making everyone who sees it scream and shudder in fear.
That or one with a feature of a remote control off button, might appeal to them to keep pintsize from causing too much havoc. Small comedy of errors with it, and possibly the roomba getting control of it. But meh, that's probably too cliche.
