Was at my local Lego store 3 days ago and was directly told that this set and the Haunted House have been "officially retired". Of course, the staff know nothing, but what the 2 people I spoke with appeared certain about was that they can now "only be picked up on the secondary market".
Personally I waited on the Sopwith camel for investment, I`ve now bought a stack of them through separate orders, I love this set and from waht I`ve seen the people who also love it will be willing to pay quite a premium for it. I missed the Haunted House though, that one I really screwed up on. Figured it would be out till end of year, big, big, big, big, huge mistake!! Gah!!!
