Guitar Hero III, why is it more expensive on Wii?

[Josho]

I just bought GHIII, and after buying it, I realised that it is £15 more on Wii then Xbox and PS3, dunno about PS2.

PS3 & Xbox £50
Wii £65 

WHY? Wat also annoys me is that you plug your Wiimote into the guitar, so when you activate "Star-power" it's the Wiimote that has the tilt sensors, wheras on the other two, its an actual controller, and thus must have sensors in that and therefore has more technology.

Why is it more expensive on Wii?

I find that a bit out of order.

id think thats why, because it requyers [sp?] you to add an external controller

but yeah it does sound screwed up too
