Super Stardust HD -- what Blast Factor envies?

Helsinki based Housemarque has been working on a new PSN title called Super Stardust HD, probably a follow-up to their original Stardust that was on the PC. Housemarque also helped with the PSP title Killzone: Liberation which is supposedly very fun (don't got a PSP, so can't give my impressions). The title is rumored for a summer release over in Europe -- no word on any US dates, but we'll cross our fingers.

What do you do in the game? Well, you hover over a series of planets (one at a time, silly) and... shoot stuff. Different weapons have different impacts on the things you shoot (amount of debris, power, etc), but in the end your ultimate goal is to destroy it all. We'll keep our eye and ears open for more info.
