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 The 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.
