It's a seasonal thing - I'm sure they'll be back on their website come next winter.
I have several pairs of Lundhags and wouldn't really recommend their winter-type boots anyway. What they are best at is the old-fashioned shell-type boot that one can wear with extra socks.
I have an old model called 'Forester' which is most like the 'Scout' in their current range. With the right socks I was OK down to -10C on a day hike. Anything colder I have other boots for.
I also have a pair of 'Siberia' which have thinsulate lining, but don't like them anywhere near as much.
*By the way, Husky Ski is only for skiing - they're not good to walk in.
