Looks awesome! Soft openings are rumored for later this summer - August-ish. Supposedly Disney wants M:S up and running officially by Labor Day. But we all know what happened with Test Track so don't hold your breath.
Oh finally - I have been checking that site for new pics and was wondering when they would come up. Cool - they have pictures of a commericial shoot of the ride too that they have been shooting at EPCOT.
