Despite
Harmonix stating of SingStar Beatles, "There is no such thing as
Singstar: Beatles. That is a rumour", in response to an
MCV story about the games, it now appears that it's less of a rumour and more of a packshot (pictured).
Kotaku has
posted the shot and stated, "It includes a regular copy of T
he Beatles: Rock Band and a pair of wired microphones...". It's also clearly marked "SingStar".
Apparently, "It's out later this month, is definitely targeted at the older crowd who are more likely to sing than hold a plastic guitar, and is most likely for PAL regions only."
So, basically, it's
Beatles Rock Band with SingStar branding and without instruments.
