Hi, I agree with Pics2 that this is not the right place to ask, but anyway if you use fast cards the wait is shorter:
Using SanDisk Extreme Pro 16GB, 90MB/s, Uncompressed RAW 14 bit, camera on CH (about 4 fps)
After 16 continuous shots the camera slows down to a little less of 1 fps if you keep the shutter pressed. If you release the shutter after the 16th image, it takes about 14 seconds to process.
Changing to 14 bits Lossless compressed, the time to process go down to less than 9 seconds (after the 18th image)
Using 12 bit lossless compressed, it takes a burst of about 25 shots and takes less than 7 seconds to process. If you keep the shutter pressed after the 25th shot, it continues at a rate slightly above 1fps.
Regarding the issue of using 12 bits instead of 14, if you shoot at ISO 400 or above, you don't need more than 12 bits because the other 2 bits will be noise (Check the measurements at DXOMark)
There is an option to go faster, using the 1.2 crop mode (uses a sensor area of 20x30) you could go up to 5fps with burst above 30 shots (12 bit, lossless compressed) and process time about 6 seconds (for the 30 shots) or keep shooting close to 2fps. With this mode you get 25 Mpix images, much less than 36, but above most of the other comparable cameras.
I'm not a wedding photographer but I would assume that it is acceptable. It could be an issue with sports / wildlife though.
