Does anyone know how large the infantry pieces will be. If the fighters are the same size as the Armada fighters I would put them around 15-18mm?

which is good because Im hoping they will be compatible with 15mm.

Does anyone know what the sizes are though, or perhaps has access to someone who might know.

Don't know yet, but I am hoping the at-st will be compatible with 6mm scale.

The reviews have said the fighters are slightly larger than the Armada fighters, but that's all I've really seen for sure.
