Replacing Canon G10 system, which point/shoot?

I am starting to look at the options for replacing my wife's Canon G10/FIX housing system. Her absolute #1 requirement is that the new system MUST MUST support TTL in the camera's 'manual' mode. The Canon G10 does not support this and it aggravates her to no end.

#2) She would like to keep her S&S YS-01 strobes (and ultralight arms/etc).

#3) requirement would be decent 1080P video.

Suggestions for a camera and housing?

Thanks.

The Sony RX100 in Nauticam housing is the best choice, it does of course need additional wet lenses but it is the best compact on the market

Other possible option Panasonic LX7 in Nauticam housing slightly better video but overall picture quality is not as good as the RX100

Of those the first two have the best video capability

There is a hack for the G10 using CHDK and a script to run TTL in manual by the way

why not move up to the OM-D
