I don't know if anybody has mentioned this so far, but doesn't the release of an H-B W.12 (Early), rather indicate the likelihood of an H-B W.12 (Late) at some stage? I'd hold out for that on the basis that WNW are maybe likely to stuff the box full of more goodies to tempt a second purchase!
My wishlist would be for a Dolphin, some BE2s and some Austro-Hungarians - Phonix, Berg, Starstrutter or maybe even a C-type.
