Is it too late to quickly re-brand as 6 mm/8 mm scales?
In many ways, wargaming scales are very arbitrary (and who's to say we know how tall people are in the future in any case?). But it would be nice to have a collection that's at least approximately internally consistent. Perhaps the recent interest in community opinion and presence of designers at other events can be an avenue for people to at least discuss scale with them? Who knows, it might have a subtle effect and the designers might get away with 8 mm Tactical Marines but Epic-scaled non-Astartes?
It's interesting that there don't seem to be any major, well-known titan miniature games at the moment. I really hope that they do a cracker job on this one but at the least maybe it'll (re-)stimulate community interest in making another one?
Like others have said, I think plastic starting titans would be ideal: plastic is easy to modify and build with, and is cheap en masse (as well as being a hole in the market). Like with how Warhammer Fantasy and 40K should have been, mass produce the common things in cheaper plastic, and make the 'character' or rare and unusual things in more expensive resin (as metal was in the old days).
Aside from titans and certain Xenos species, I think the alternative market has really burgeoned thanks to the likes of @moredakka; I think this market will continue (and hopefully increase!) because of the relatively stable niche it currently has and because of the high quality of releases. And current producers will already get a head start if they make it a titan-only release since people will have to go somewhere for infantry and tanks...
