Well they tried to have a deal with Sony to have the Oscorp building feature in the Avengers but it was too late by the time the deal was ready. I know they aren't actively trying to get the rights back but I imagine they'll strike up deals in the future so they can have crossover films like the rumours going around about World War Hulk coming to the silver screen.

And with superhero movies being "in", it's not going to happen any time soon.

i know it's unlikely, but a girl can dream can't she? ^_^

once upon a time, an Avengers movie seemed like an impossible dream.

whatever happens, i'll be in line to buy tickets to all the movies, day one, whether they share a universe or not.
