Just as we reported months ago the real availability of Radeon 2600 series is expected after middle of July. There are two reasons for the delay one is a tight availability of the final A15 silicon while the second more important is the lack of WHQL driver for the card.
The driver was expected last week but it still didn't showed up but ATI's Add in board partners are hoping to get the driver and have the cards in retail stores after 15th to 20th of July.
Radeon HD 2400 PRO cards are available but even the HD 2400 XT are still on the ice. Well, give them a few more weeks even I can understand if you are tired of waiting for them.
