If I had to pick one winner, has to be toh. No questions asked. Aamir and big B, huge scale and aamir's epic script sense.
Tiger zinda hai will take an earth shattering opening, sequel to the biggest BB of 2012, salman's action image, yrf and katrina........if all goes well should target dhoom3.
Dwarf is good on paper, SRK will give it a strong start, has a list actresses too, will be promoted on a huge huge scale, with a good storyline, and solo release, 250+ is the target.
