The original Rock Band was pretty revolutionary in terms of console accessories, offering deep-pocketed gamers the chance to croon into a mic, jam on a Fender Stratocaster, or bash seven shades out of an 80s-style drumkit. Rock Band 2, out this September, will add a larger set of drums to the mix - but that's not enough for us. We're already dreaming about the possibilities for Rock Band 3. Read on to discover the 10 instruments we'd most like to see included in future instalments.

10. A Grand Piano

It probably wouldn't be that hard to engineer some form of lightweight keyboard - but then where would the fun be in that? We want a full-sized grand piano - something so big that it completely dominates your living room. Just think about how much hassle it will be getting the damn thing back from the shops - everyone will notice you struggling under the weight of a massive box, and then they'll know how rich you are. Once set up, you'll be able to tinkle away to tracks like Beethoven's Moonlight Sonata, or the complete works of Elton John. It could even come with its own piano stool (r.r.p £79.99).

9. A Harp

Now this is a classy idea: rather than featuring strings, the Rock Band harp would feature sophisticated lasers to detect the movements of a player's fingers, allowing them to plink away at a sweet selection of angelic melodies. The bundled tracks would basically consist of all the irritating background music you've ever heard at weddings, corporate events and New Age soap shops. Excessive use of the harp-lasers might lead to severe radiation burns - but when you're not using it for games, the device could also function as a sort of uber-powered fly zapper.
