This is the official trailer for Guitar Hero Live. It's Guitar Hero, but not as you remember it. I'm quite excited.
I won't say too much. I haven't seen it in action, but Kotaku UK's Keza McDonald has, and she's got a more detailed preview going up on the site at 9am this morning, so check back for that.
For now, watch this. Be confused, be excited. I'm so ready for both Guitar Hero and Rock Band to be back. Time to get the band back together.
