Regardless of the final budget as in the first film it was 150 million that does not count for advertising at all. The first film was just under 200 million with advertising and they need to spend about the same amount advertising the next one.
Personally I think it could be done for 200 million for the films budget and another 50 million for advertising the film.
Also, they need to get the Imax version of TF2 ironed out sooner, it almost did not happen in my area for the first film ( Seattle, Washington ) but I'm glad that it did, the picture was 60 feet tall and 80 feet wide and 12 thousand watts of stereo power and when Megatron came tearing through that old building after sam it really sounded like wooden planks were crashing and falling from the ceiling, Ironhides weapons had a lot of bass to them and it was awesome. One of my favorite scenes ( See here
