Rumors are beginning to sprout up claiming that Marvel is planning to being including ten minute mini movies before their feature length theatrical releases. This mini movies would feature more B-list characters, such as Dr. Strange, Iron Fist, Luke Cage, or Black Panther. The thought process is that it would help create exposure for lesser known characters, by putting them before their big budget flicks.
Imagine if there was a ten minute Dr. Strange short before Iron Man 2, it would have created tons of awareness for the character. So I think that if this rumor turns out to be fact, that it will be an awesome idea.
