In reply to Juliankitesurfer:
I have them, but they are brand new and I've only used them once. I used them on a glacier hike with crampons. Here are some of my impressions so far:
They are quite light weight. They feel medium+ stiff (less stiff than for example La Sportiva Trango, but much stiffer than regular hiking boots). Medium ankle support. Not bulky at all. Comfortable to wear for an entire day, and so far, no need to break them in. Also, very comfortable to walk in! I see myself choosing these boots for almost every activity in the mountains. I've ususally chosen low cut gore-tex shoes for nearly everything because I hate bulky boots, but the Scarpa Ribelle Lite feels light with a tight fit, and I want to wear them. They worked well with crampons, but I don't really have anything to compare to. I seemed to be the happiest and driest at the end of the day, but I was also the only one wearing gaiters. (the weather was really bad)
The German review says that if you are USED TO wearing shoes with built in gaiters, you should probably put on short gaiters. Like any other shoe/boot without gaiters, the snow will work its way down if you wear them in deep snow.
All in all, very happy with them, and can't wait to wear them more. I'll try to remember to report back in two weeks time when I've gotten the chance to use them more.
