I'm pleased that yours is on it's way. I went for the 5x4 and there is no date for those yet, as understandably, they wanted to get the smaller formats out of the way first.
It's been a long wait, but I think the guys have had a pretty tough time sorting out the logistics and business side of things.
Anyway, in the UK, I think a 5x4 pinhole is a summer camera, rather than a winter one.
