Every physical aspect we posted about for the "rumored" Guitar Hero cab are present in these pics: At the top of the cabinet, you'll see the Raw Thrills and Activision logos, and, what is that on the left - it's Konami's logo! The LED lights are clearly at the bottom of the screen and appear to change color - maybe just at random, but perhaps along to in-game occurrences. Finally, the screens are wide and it's easy to believe these rank in at at least 32 inches.
Kind of a cool-looking cabinet, but the details of the actual game is what will make this announcement interesting. Will it have some kind of Internet competition aspect, making it Golden Tee with a guitar? How will it receive song updates? Will bars be willing to install a device like that that will just compete with the jukebox for loud music supremacy?
Also notice the long-rumored American Idol arcade cabinet in the background of the shot, bearing the name "Star Studio." I remember hearing awhile back that this was going to be one of those "burn your karaoke performance onto a DVD" sort of deals.
The IAAPA show begins tomorrow, so any official announcements about either game will probably come out around then.
