Didn't see an announcement on it here, so thought I'd pop in and let you folks know that Quantum Conundrum is now available on Xbox Live Arcade and the Playstation Network for 1200MSP/14.99USD.

It's receiving wonderful reviews and there's also a demo of the game available if you want to try it out before buying (just a bit over 10minutes long). I've played through it on PC already and will probably end up double dipping soon. Cheers.
