The previously teased firmware update for the Canon 7D is now officially set to be released in August.  The firmware set looks to be a mighty big one with a RAW image burst buffer that now allows 25 consecutive images over the previous 15.

The firmware update will also provide support for the Canon GP-E2 GPS receiver.

Another big feature for the 7D will be the addition of manual audio level adjustment, which is something 7D HDSLR shooters have been wanting ever since the camera was released.

There are a whole lot of additional features fully detailed in the press release below.  There is also a (rather hokey) video preview of the new features on Canon's website.
