Unfortunately I don't have a release date and the beta firmware is still undergoing testing and updating. We do not ever provide a guaranteed release date of firmware for any products so the firmware will be out and available to the public when it is done with all testing.
The frustration is that many (myself included) feel that the entire point of a beta website realeasing beta code is so that the public can participate in in the testing processes. While I understand the importance of not tossing our every build compiled (though some sites _do_) it seems dlink treats thier public betas as more like release candidates than betas. We dont see much into the beta path ... and generally have no idea if our opinions are getting a voice.
There are some big bugs in the code that I'm not even certain have been acknowledged yet.
