A77/A65 HS Buffer Depth in 12MP mode?

Anyone with hands on experience with A77 or A65 know if the shot buffer is deeper if the resolution is backed down from 24MP to 12MP?

I.e. I can only get 13 or 18 images (depending on JPG Mode) shooting at 12FPS at 24MP.

Can I get more than 13 or 18 shooting at 12FPS if I've set the resolution of the camera to the 12MP (or even the 6MP) mode? If so, how many?

Anyone with hands-on experience try it?

Also, I wonder why there has to be a buffer depth hit with RAW+JPEG when compared to RAW. Why can't these guys write the firmware to tag the RAW images that need to be converted and convert them to JPG during "idle" time? (Could cause problems when the card is ALMOST full, as there may be RAW images taken which there is no room to convert.) but this sounds doable.
