I reckon it looks pretty interesting. The ramps tunneling through the backboard is reminiscent of LOTR, but I can't recall seeing any other pin with anything quite the same. Great aesthetics too.
The only concern I have is if Iron Man's balls will be prone to rust?
Austin Powers has the same ramps tunneling through the backboard.
i doubt that any one could make a pin without some one saying "that is a bit like blah blah"
Unfortunately its got to a stage where every thing has been done on a pinball before. 
The only thing left i suppose is a play field that changes. i.e the pop bumbers disappear below the play field and some drop targets come up or the ramps change shape. or every time you press the start buttton the playfield is set up randomly. (sorry guys i am a bit drunk at the momement LOL)
All of the above is probably possible but at what cost?
Imagine the price tag?
The advert would go something like this, " here it is, transformers the pinball, no 2 games are ever the same, only $50k, "
as i said, I am drunk so when I read this in the morning i will once again tell my self "DO NOT POST ANY THING ON AP WHEN I HAVE HAD WAY TO MUCH TO DRINK" 
Chatting with John Trudeau this past weekend, one of the questions I asked him was if there were any features they never were able to get designed into pinball as in new ideas. His basic response was "no matter what, the game revolves around that 1 1/16" ball so there's only so much you can do".
