The only thing so far that boots for me is http://www.raspberrypi.org/downloads/ raspbian debian wheezy 2015-02-16, otherwise I get the "rainbow screen of waiting"

Ditto here, ...I think the system images aren't ready for this new board?

Brand new Pi 2 and my first Pi, downloaded fresh images of openelec and raspbmc, and I get the same colored screen on boot using two different memory cards. Something tells me we aren't ready?

Sadness...
