Not entirely convinced about the Beatles edition of ‘Rock Band’ – those twangy riffs just don’t look all that satisfying to play along with.

But looking at the jaw-droppingly slick preview clip that has just surfaced, ahead of the game’s release in September, Harmonix are throwing a huge budget behind this game.

Factor in the billions of dollars generated by previous games in the series, and The Beatles’ generation-spanning global fanbase, and we may well be looking at the biggest-selling video game in history.

What with Project Natal for the XBox, it’s been an exciting week for gamers.
