If the endless amount of platform combinations between Rock Band and Guitar Hero III have you stymied already, here's a little tidbit to make it just a little bit harder to choose: Guitar Hero III wireless controller are going to be available early next year for all platforms. Rock Band has wireless controllers on the way in a similar time frame for both the 360 and PS3, but for some reason the 360 version costs an extra $20, so hopefully Guitar Hero guitars keep some better price parity.
