a new realise pin 2k (with screen over playfield like swep1 or rfm) and a interactive 3d lcd back glass (like an oversized colour dmd display but better) all rolled into one.

Or a new concept like a playfield that has some sections that are clear with 3d interaction (like having 3D Nintendo screens projecting up from the playfield)

I know some people say it's not really pinball but if you look at it that way then a dmd machine is not really pinball. (since pinball was originally all Electro Mechanical now wasn't it.)

Pinball had evolved over the years, maybe some more changes could bring it back again.

Well we can all have a dream can't we. 

But yes some new pin 2k titles would be great
