I think we will see a very strong Marvel line up for DI2.0, if we get 6 to 8 playsets, I'm thinking at least half are going to be 3 playsets, my guesses would be a Captain America (captain, falcon, black widow, hawkeye, nick fury), Guardians of the Galaxy (the 5 main characters) and maybe a Spiderman playset (could be tied in with the amazing spiderman movie but it could just be a comic spiderman tie in)... disney infinity is supposed to be used as a way of promoting new games for the new releases, its easier to make some figures/playset for a well established game than to keep making rubbish games that lose money.
I'm guessing Guardians will be a playset with 5 different figures, they want to promote these "new" characters, yeah lots of us don't know them but i think by the end of the summer, they will be huge characters that the kids will be into.. they aren't really aiming DI at adults, they want video game tie ins, it makes sense to use the characters from this year, i can't see them doing an Avengers playset with Thor, captain, hulk, iron man as they can easily spread that out to 5 completely different playsets (which makes more sense from a $$ point of view.,. i'm guessing at a age of ultron playset next year for 3.0... this is a long range plan, they aren't going to throw everything out at once...
