great potential for a pinball

Fk me what a movie this is going to be!!
The new trailer is one of the best trls I have ever seen, Hulk rescuing falling Ironman is insane, Ironman, Thor and Captn America in the woods and fighting..wtf and wow.
Bruce Banner..."we are not a team we are a time bomb"....superb line, looks like tony stark won't get all the good dialogue.
Rumors have a possible cameo from another Marvel hero or two and possibly another 2 villians to go with LOKI.
If the pinball is anywhere near as good as this action tentpole is going to be then wow...can't wait to play one if it is made.
My predicition is this will be the biggest film of 2012 by a long long way.
