A wee update, I'll pop this in the
OP as well:
Will Hayes was kind enough to reply to one of my periodic hair-tearing sessions on the
AT FB group(I've removed most of the back & forth and just kept the
IMO two most relevant bits of info):
So this is both good and bad from my perspective. Good in that we have some fairly solid confirmation of 8mm-ish Marines, so my measurements of the Titans should be about correct. Bad - or at least disappointing - in that they've chosen to go with a simple downscaling of existing
40K models where that's required(such as the Xiphon and Leman Russ wrecks on the
FW terrain tiles) rather than establishing a consistent scale based on the "real" numbers for vehicles.
The
TL; DR takeaway then is that Marine infantry(should we ever see it) and the Titans themselves will be pretty close to "truescale 6mm", but beyond that anything we see will have a lot of variance depending on how their
40K models are sized and proportioned.
