not to mention AVI is a container, not a format.
but yeah, dumb question
it will be some lossless format, like the current one, and probably, if it's going to be used by MAME, in a CHD container, like the current one as that provides streaming and checksums.
it might not compress amazingly well, but the goal is to save this data for future generations at the best possibly quality it can be captured at today without throwing away anything that is captured (which means if captures are done from different discs in the future no additional artefacts have been introduced that could get in the way of comparisons)
