Batteries must be kept warm. That requires changing batteries every half an hour or so in really cold temperatures (High Sierra in winter, for ex.). I have spare lithium batteries (5 of them) but I don't appreciate changing batteries in mid pitch on a climb...There are a few cameras on the market that are sealed offering weather resistance to 14 degrees F....
As radson has said above, you need to get over the minimum operating temp thing - it's just a number on a company page. It's irrelevant how an old mechanical SLR did in the cold. Any modern cam will have enough electronics to be vulnerable to -10C or whatever. Weather-sealing is irrelevant to the issue of cold, I can't see why you think that matters. WS keeps out moisture and dirt, but the best sealing in the world won't stop the whole unit getting cold if left outside in -10C. If you don't keep your p&s inside your jacket then, yes, it might need a new battery every 30min, but I can't see the sense in doing this. It's an issue of usage, not gear specs.
The only mechanical/electronic thing that helps with extreme cold, that I have found (in a dozen Antarctic expeditions and numerous Himalayan/Karakoram/Andean expeditions above 6000m) is that the higher-spec DSLRs have a bigger stronger battery and this does make a difference. But I don't want to lug one of those big things up that high.
The Cannon Powershot line is OK. The G-12 and G-15 are good cameras. but their minimum operating temp is 32 degrees F.
The Canon G15 is probably the closest to what you want if a viewfinder is a must. I've come back around to preferring an optical viewfinder, but I've still taken dozens of great shots with just a lcd screen. If you could get around that, and your gloved hands are not too big for an RX100, you won't get better p&s image quality than that camera produces.
So if there is nothing available on the market, fair enough, we will have to live with the old cameras we have.
Maybe think again why there is 'nothing' on the market that you
want? The fact you lugged your mech SLRs around on a big trip and didn't use them, and that you think that weather sealing will help in extreme cold, leads me to think you might want to re-think what you do, not what you have, or don't have.
I know most of the cams out there are compromises, but you have to be realistic. Cheap crap aside, the best modern cams in each category are hands-down awesome, both in terms of capability and how little they cost.
