Yeah, I heard about this, and I've been skeptical since Day 1:

1) The source for this apparently comes from information Shane Black was given for Iron Man 3. However, there's no reason he would need to know this since it has absolutely no impact on his film.  Not only is the Hulk not in his movie at all, but there's no way for this to be built up to.  The source says that the post-credits tease at the end of Avengers 2 is the Hulk alive in space drifting towards the planet that will be used for the Planet Hulk movie.  Considering how secretive Marvel, Disney, and Joss Whedon were about details concerning The Avengers (particularly the contents of its post-credit scenes), this seems like a weird misstep for them if true

2) Disney would not greenlight this. Consider their most recent bomb, John Carter.  The movie, while it didn't do terribly at the box office, is still a huge box office bomb because of its over-blown budget.  Apparently, John Carter needed to make at least $600 million just to break even.  Now consider what the premise of John Carter was - your tough, heroic American man is transported to a war-torn and dying Mars where he unites the people, kills a tyrant (who, I kid you not, is the king of the Red Martians), becomes hero to all the Martian people and, at the end, becomes Prince of Mars.

...that sort of sounds like Planet Hulk, doesn't it? Disney already blew millions of dollars on John Carter (the highest estimate says they lost $250 million), so they're not going to be all that excited about greenlighting another sci-fi/fantasy epic where the hero does the exact same thing. Not to mention that a Planet Hulk movie would have to be much more expensive than John Carter. After all, Taylor Kitsch standing around for two hours is a lot cheaper than having to animate the Hulk. Have you ever wondered why the Hulk, even in his own movies, is really only in two or three scenes? The majority of the movie is made up of Banner on the run and some scene with villains and/or side characters. So a movie where the Hulk is present in just about every scene is going to be incredibly expensive to begin with; then throw-in all the extra animations and such that comes from setting the film on an alien planet...

Yeah, don't expect Disney to agree to a film that has to make more money than The Avengers just to be profitable, especially when the previous two Hulk films combined have made less than Iron Man 2 (and didn't make back their budget on the domestic market).
