I would have liked to have seen something done with Q...but I guess he was already used for Star Trek/Legion of Superheroes.
There's still seven issues of Assimilation
to go. If Q doesn't show up, I'd be surprised.
(If Q does appear, I wonder if they might suggest that Q and the Celestial Toymaker are one in the same. They are
very similar, when you come right down to it...)
