Here's an article about the lack of Marvel tie ins. For the most part, it's a refusal to reprint any of the original comics for those dopey reasons that it would be "confusing." But anyway, Disney has not marketed the movie as a Marvel film or "Based on the Marvel comic" until recently, and even then, those commercials stopped airing as soon as they started. They're not even releasing the Disney Infinity figure tie in under the Marvel banner (that is, I swear they are going to release some under the second Disney series, and I swear I've seen them). Not to mention that BanDai has the toy rights instead of Hasbro. They're clearly trying to distance themselves from Marvel for some reason, even though most of the audience will know it's based on a Marvel property. Then again, with Captain America 2, Guardians of the Galaxy, X-Men, Spider-Man 2, I can see why they don't want to seem like they're flooding the market to the more casual film goers.
