Thanks! The 28mm US M11 General Early walker kit and the German Valkyrie walker kit have been released and are available through Brigade Games, several other etailers (including in the UK and Germany) and direct from Company B:
http://www.companyb.biz/There are also conversion and detail kits for those to let you create a variety of support variants, decals, TC figures, and so on. The next out will likely be the Japanese Type 38 ShiKi combat walker which is a master mold production phase, and we've also protoyped British, Italian and Soviet combat walkers and accessories.
We are also doing other Late WW2 accessories, like the recently released UhU/Owl night fighting vehicle accessory:

UHU Eagle Owl conversion set.
Introduced in late 1944 the 60 cm infrared searchlight with a range of 1.5 km was known as the"Uhu" (Eagle Owl), they guided IR sight-equipped Panther tanks to targets that were out of range of their own smaller infrared searchlights.
German Night Fighting Set:
Includes UHU search light with 2 mounts and 1 Falke.
