There is no mid-July estimate. The current optimistic estimate is mid-August. Add the necessary mountain of salt, and you will understand that it is unlikely to ship this year.

They are still working on the case.

When they finish, they will have two options: go directly to mass production, in which case they will ship in September, but they won't know if it will work or not until then. Or they might decide to make another model case, which pushes everything by a few months, making November as the earliest option, and sometime in 2010 (or later) as the likely option.
