I'm interested though.
What are your realistic expectations of what Gohan can add to the story ?
Let's say he gets strong, so what ? We already have Vegeta.
The prospects of Trunks coming back open up for a big "quest".
But what can Gohan bring ? To be mixed with a new universe, that is.
The only thing I can think of, is that Gohan's SCIENCE discovers some sort of space time continuum issue, or some universe merging hole or whatever, that would lead them to go investigate.
But how would Gohan "back in action" push the story forward at this point ?
He is not interested in the big penis contest Goku and Vegeta are having. So I'm not sure why you guys want him to be at the same level.
