They probably are interested, but nobody knows the answer yet. I'm sure that when the final reviews come out (especially the Anandtech one) we'll find out.
I see; I assumed it was Optimus that did the switching, but if it's Apple's own implementation then it probably won't work in Boot Camp. Here's hoping...
I doubt there'd be Optimus support in Bootcamp. Optimus support is something the manufacturer has to build into the laptop, and, as with the ATI solution before it (6750/6770) it is supported in OSX but not Windows.
Apple generally has poor quality drivers in boot camp... Battery life goes from 6-8 hours in OS X for me to 1.5-2 in Windows 7 with the same settings... graphics switching is not possible in Boot Camp. Wifi additionally doesn't work as well in Windows 7 for me.
You never know though, maybe Apple might add it to this MacBook Pro or there is a way to add it yourself.
