Yes they officially dropped "Of Mars" from the title. Disney changes a lot of movie titles so this was not surprising. Rapunzel to "Tangled". The Bow and the Bear to "Brave", The Snow Queen to "Frozen". It is a marketing gimmick, anything with "Mars" sounds too sci-fi. Anyway, as another poster has commented, this is Andrew Stanton we're talking about. Director of "Finding Nemo" and "Wall-E". He is a top-notch guy that knows good filmmaking. It may look incredibly dumb, but I have 100% in this guy. He has never worked on a poorly reviewed film in his entire career (according to Rottentomatoes.com). And as how do we know the title was changed? Just google it, IMDb, Rotten Tomatoes, Wikipedia have all been updated with the new name, "John Carter". This isn't a Prince of Persia repeat, guys. This is PIXAR filmmaking goes Live Action, similar to December's "Mission: Impossible 4" by Brad Bird. And that was spectacular.
