Nice to hear the Guardians of the Galaxy will show up, alongside Galactus. Their previous appearances on Ultimate Spider-Man and Hulk and the Agents of SMASH, respectively were pretty good so here's hoping this episode will turn out well. I'm not that excited about seeing another Avengers versus Guardians of the Galaxy story though, but it's better than nothing I guess and it could lead to some good stuff.
As for the other one... not sure what to say. I wonder how Ant-Man will look, and it's neat that he'll finally appear again somewhere (though I doubt he'll actually join the team, which he should), but Falcon's mom? More unnecessary and forced humor which most likely won't work in the end. Hope she's brought enough of her home-made cookies this time, so that Falcon's "room-mates" or whatever he'll end up presenting them as won't have to fight too much... Granted some of the episode descriptions so far have left out some details which ended up making the episodes a little better (such as, "The Ambassador" didn't mention the Cabal will show up), but I seriously doubt anything really worth watching could come out of this premise.
