Where are you hearing that staind are even potentially a thing any more? Last I was following was none of the members had any interest in getting together to put anything together... I love staind, so I hope there is something in the works I've missed!
Nothing specific, just an Interview from 2015 in which Aaron Lewis stated that they definitely record another album in the future but are fully satisfied by their current works.
It was more like a wish, since his Baritone guitars were available even when Staind's popularity went down since their self titled album and Mike always was some kind of figurehead for PRS' heavier part.
