Steve, it does not come out on the 23rd. It will be announced on the 23rd.
People seem to think it'll go on sale June 30th or July 7th.
Personally, I think it will be July 7th. It keeps with the "two weeks notice" trend. It keeps with the "Haha! You heard about it first from White Dwarf" trend. It also keeps with the "our new stuff comes out on the first Saturday of the month" trend.
It'll be July 7th... The same day as the M13 Prerelease....
