It was never going to be pretty - and with Guitar Hero World Tour set to go head to head with Rock Band 2 this autumn, the rock 'n' roll royal rumble has begun in earnest.
Speaking to Eurogamer last week at Game Convention 2008, Guitar Hero director Brian Bright scorned Harmonix' attempts to match the feature set of the World Tour drum kit, while ostensibly clearing up the mystery surrounding the rumoured new peripherals for Neversoft's title.
"I don't know how far ahead they planned that - we obviously revealed [our drum kit] much earlier than they did," said Bright, referencing Harmonix' plan to release separate clip-on cymbals for Rock Band set-ups.
"I've a feeling there was a: 'Oh s***! There's cymbals! How can we put cymbals on our kit?' That would be the easiest way without having to rewire everything and re-engineer the entire circuit board."
