I wonder what the new 3D technology will add to this 'medium' in the years ahead 

You have to admit that some of these table 'drawers' are very talented and if they hook 3D into future releases- well you never know 
In relation to appearance - all they need to ( for this pinball emulator ) do is create the 'depth' rather than having things 'come out' towards you - so thats not too hard.
And bear in mind that glass-less ( wearing no glasses ) 3D is here as well - soon.
