@ Fossy: I'm pretty sure the main reason he said that is because if he allowed it, everyone would say the Phineas and Ferb 2013 movie. So, he didn't allow it so that everyone wouldn't say the same exact thing.

@Platyborg: Well, the Phineas and Ferb 2013 movie is an upcoming movie that's coming to theaters, and even though it doesn't have an official plot yet, it is said to be a mix of "animation and live-action". The Phineas and Ferb characters are said to stay animated through the whole film, too.
