User blog comment:X-Men Are Cool/Next Year's Crossover/@comment-26618197-20171130171758

Have you forgotten that Mon-El is already married?

Anyways, I do like this idea however I think they want to do one or two more crossovers before the world merge. The world merge is a huge event, something that would be extremely hard to top. It's the day memories alter, a day to celebrate. It's not a simple invasion. For it to hit hard like it's supposed to everyone needs to meet everyone else and become like family. For the third crossover I think they'll turn the place they went to last crossover into the Hall of Justice.
