So, not a whole lot of new stuff shown for MU at SDCC. There was news that the line would be transitioning to a new name "Avengers" in 2014. They claim that the figure quality/selection will remain the same, but it will be interesting to see. I think this may be the Avengers Assemble line, which sort of follows the toon but doesn't necessarily have "toony" figures. As for what was shown, it sounds like the following are on the way (at least that we didn't already know about):
Also, the 3 packs will be ending with the Asgardian and Astonishing X-Men packs that were previously announced. I didn't see any news about the comic packs, but I'd be guessing they are going as well. Not sure though.
They are saying that the line name is changing because retailers recognize Avengers better than Marvel Universe, and this will allow the figures to get to the stores more frequently. I have to wonder if the MU line as we know it is all but done now though. It seems to have sort of been fizzling for awhile now, and I can't say the lineups have been super exciting (although I do want Cloak and Dagger from the next wave). We'll have to wait and see what the Avengers line brings I guess.
