Touring Bindings without Touring Boots??????

Depends what kind of binding you get.  Fritche and Marker and atomic, etc all hold an alpine boot as well as a touring boot.  If you buy something like naxos or others, that use two pins on the toe, then now, they won't work.

Naxos work just fine with alpine boots.  So do FRs and the Marker AT bindings. 
The Salomon/Atomic binding won't be available until at least next season.

You will be able to ski and skin in alpine boots.  AT boots are usually lighter and are designed to walk better than alpine boots.

All the aforementioned brands of bindings will work with an alpine boot. The biggest differences are generally weight, sometimes a rockered sole, and a generous walk mode that lengthens stride and increases comfort for long tours. Unless you are doing those really long tours, ski mountaineering, or want light as shit, then AT boots aren't necessary.

Exactly. I've been going without AT boots for three years and haven't had any issues. As mentioned though, the longer the trek, the more you will notice it.

just to say the salomon tourers will be available early jan 2012 in select resorts, its like the rocker 2 realease last year. same with the goggles in north america

sick thanks! good strong touring binding then that's good for my 186 4rnt EHP's now that allow u too charge but almost stay under 450 if possible?

95% of the people who own dukes don't own touring boots.
95% of those people don't tour either.

hmmmm, I bet that way more than 5% of duke owners tour (at some point). But that doesn't matter.

OP, I'm now on my 8th seaon touring in Alpine boots. I almost went for the Dalbello Virus last year, but it wasn't stiff enough for me. Generally, I don't trust walk modes either. BUT, I need my boots to have vibum soles. If you hike around scree as much as me, that shit will wear down your boots and you will wonder why you prerelease. I'm really digging my Ace of Spades. When I hike and/or tour, I just unbuckle the tops of my boots and leave the lower loose. I don't generally do really long tours, but I've definitly bagged 4k plus skin tracks with this setup. It's worth it for the down. It's all about the down!

does touring from your car to the lift count? lol i remeber selling dukes the year they came out and this is probably what most of them are used for....

i ski alot of backcountry with dudes and i have fulltilt boots and it works perfectly fine man
