Ars Technica has posted a thoughtful and thorough review of Guitar Hero: World Tour, Activision Blizzard's attempt to move the Guitar Hero franchise into the full band sim space Rock Band elbowed out for itself.
I admittedly haven't followed Guitar Hero: World Tour, having given up on Activision's ability to make a satisfying Guitar Hero game sans Harmonix after the execrable Guitar Hero 3 (and after Harmonix changed the game entirely with Rock Band). That said, Ars thinks the game holds its own with an incredible set list, and I was intrigued to hear that the actual hardware ‐ the plastic guitars and drum sets — has changed significantly, and largely for the better.
Here's Ars' thoughts on the touch strip.
The biggest addition to the guitar is the touch-strip below the buttons, and it's interesting. While holding a note, you can slide your finger up and down to add a very electronic-sounding "wah" effect, and this works just like the whammy bar. There will also be sections of songs where you can slide up and down instead of hitting the strum button, and those take a while to get used to: the "buttons" are all together with a small ridge between them, making finding the "home keys" very difficult. You also can't see the colors on the pads because that section of the guitar is indented, making it hard to use even while looking down.
They also thought the three pad drum kits was a significant step up from Rock Band's, which is the exact opposite of what you'd expect. Sounds like this one can't be dismissed out of hand.
