What could it all mean! Mystery and Guesswork abound.

Following in the fine tradition of band tie ins, Rock Band Green Day is shaping up to be a Green Day fan’s dream, even if it is a bit of a niche. The demo has appeared on Xbox Life Marketplace and PlayStation Network, with a little teaser when you exited the demo. The teaser image above show the normal instrument icons, but with one addition.

In case you’re not too hot on musical instruments, the final circle is a keyboard, which could mean that for Rock Band 3 (what seems to be advertised by the image) some sort of musical keyboard device, thingy, will be added to the line up. I haven’t got a clue how the heck you make a keyboard for a rhythm game, as at that point, you’re heading into the area of being far too musical, and not enough game.

But, with seemingly everyone I know either playing or learning to play the keyboard, I’ll probably never get a go, instead being relegated to vocals…again.

If you want to see the teaser on your telebox, go download the demo, which includes the songs Boulevard of Broken Dreams and Welcome to Paradise.
