16-17MB.

That's 15MB of raw data (10mpix of 12-bit data), plus a low-
quality JPEG for preview, plus all the other metadata, etc.
I don't expect compression; it might save a few MB (based
on estimates with compressed DNGs), but I'm not sure there
is enough processing power available in-camera for this.

You may be right, but I sure hope not. Current non-D .PEF files pack the 12-bits together is all, as others have mentioned. They also include approx 1-1.4MB JPEG in the low-qual, full resolution... that makes the 10MB size (12/8*6 + 1).

If everything scales up to 10, that'd be 15 MB or so. I think the full-size JPEG should be selectable... i.e. make it full-quality (RAW+JPEG), or remove the damn thing. Wasting 10-15% on *every* picture for a useless JPEG is irritating. Put lossless compression on it, and the size is reduced by another 50-75%.

Just for a point of comparison, the Canon lossless .cr2 on a friend's RebelXT makes 8.2 MPixel RAW files between 6.2-10MB, averaging about 7.2MB over 1500 shots. So, getting 10MB RAW files should be doable.
