I just fut coins spotted this story from earlier in the week, but Disney has new product called Star Guitarist that uses real guitars in a Guiter Hero-style environment.
It's pretty easy to dismiss a rhythm game by Disney especially when it's only available on PCs and Macs, but at least they are committing to using real guitars in a commercial product.
It even looks like they've paired up with Washburn to include an actual guitar ableit at 3/4 (Disney fan size, which maybe justifies the price tag.I've seen some noncommercial projects out there trying to do this same thing, but I think this is the first retail product to use real guitars.
