Saw, and picked, this beauty yesterday in GAME Walthamstow.
Beatles Rock band: Limited Edition Premium bundle for £49.99!
Heres the specs:
# Rock Band: The Beatles game
# Hofner Bass controller (see image below) - large scale replica of the Bass famously used by Sir Paul McCartney
# Beatles-inspired and Ludwig-branded Rock Band 2 drums with classic pearl finish and vintage replica Beatles kick drum head
# Microphone Stand
# Click http://media.play.com/ContentDocs/RB_TB_Tracklist.pdf
for Rock Band: The Beatles tracklist (requires Adobe Reader)
I didn't get a chance to play yesterday, but I believe these are all wireless (the guitar definately is).
This is still over £100 most places (Amazon, Play etc)
As a bonus I traded in my Beatles 'value' edition (the one with the first gen wired instruments) for a whopping £33.
This appears to be instore only (probably clearing them out) as it's not on the website.
I don't know if it applies to other formats, as my store only had the Xbox version.
They also had the extra LE Beatles guitars for £30 each (normally £69.99)
