Looks interesting, but that upper PF seems incredibly basic. The lock mech seems like a really cool physical gimmick-from what I can tell the ball is supposed to kick up into the toybox from the other side of the PF? The lock release effect was neat in IJ4 though, so re-using it here makes sense.
It's strange, but I never thought of Aerosmith as a band with a lot of iconography or visual style, but the game definitely looks stylish. Music is definitely solid though, just like ACDC and Metallica. Not sure about what I've seen of the LCD, but that's really going to take some time to come into its own. I know I like the way that JJP has used it to keep more information up on a HUD at once, while so far the Stern implementation seems to be "DMD+", with the display being used for pretty much one thing at a time. I have a feeling that this is going to evolve over the next few years as designers really figure out how to use the new tech, assuming that the Spike system can drive visually composed elements onto the screen.
I was looking at the feature matrix last night, and there really doesn't seem to be as much of a difference between the pro and premium as usual. There's the upper PF obviously, but even the RGB lighting is the same across the board now. Get the pro and replace the posts with real support rails and you're set?
