EXCELLENT... a few things I learnt regarding the Pro, is that the cabinet art on both the left and right cabinet sides seems to be the same, just reversed obviously to fit on each side....but looks great.

The different coloured LEDs on the LE looks great...and they seem to change colour from red, green and blue.....the pinky colour under the tesseract spinning cube looks good and both the LE and Pro have it which is good..

I would add some different colour general illumination LEDS to the Pro machine to make it pop a bit more than stock white candescent bulbs....under slings and generally under the flipper area would make it pop a whole lot more for sure....the Hulk on both models spins side to side and the arms move up and down on the Hulk which is cool. Overall, everything looks very nice.

Bring on the Avengers Pro video please !!  Thanks for putting up the videos !  

P.S - first mod I will do, is to do something colour wise with the tesseract cube...maybe add mirror pieces to it, so it bounces light off it, or add different colour to it via vinyl, or something...it looks a little plain, it may look better in person, but maybe a mod here could be worthwhile ?
