I work with Ticketmaster, this is what I know -

The show was scheduled for June 24th at MCI, the tix to go on sale June 2, Saturday at 9am.

This was 5/29. But the next day, 5/30 - they said that the event was cancelled to be scheduled another time.

Also it wasn't officially announced on Ticketmaster - it just said "major event going on sale" - the Ticketmaster people called and told us that it was Prince.

So now I am waiting for the reschedule..
