Harmonix co-founder Alex Rigopulos has revealed that the Xbox 360 retail bundles of Rock Band will all come with wired guitars, while PS3 packs will be wireless.
It's all because it costs more to license wireless technology on Microsoft's console, apparently, which would mean the overall price-tag would end up being too high - although there's still no word on what that figure will be.
"The cost of wireless technology on the Microsoft side is higher, and to be able to offer those bundles at a price point that would be reasonable for consumers it was necessary," said Rigopulos in an OXM podcast.
So, if you want an axe to grind without strings attached, you'll have to stump-up a little more of your hard earned money for a separate guitar or two.
The microphone and drum kit will be wired on all versions, though, so the 360 bundle will come with a USB hub so they can all be plugged in at once.
Pop over to our recently updated track list for Rock Band to see what you and your friends will be performing when the game launches on PS3, 360 and PS2 early next year.
