In my experience, Fireforge has been very disconstant in terms of style consistency, overall quality and more in general business direction.
Last April 1st they announced a new range of WW2 ships, in a truly oddly scale (1:1175 or something like this), and EVERYONE took that as an april's fool. Turns out it wasn't.
Even their fantasy plastic range - which was VERY promising - ended up much less captivating than what it could have been.
I cannot comment on style/strict historical accuracy since I don't have enough knowledge to do so - I must say that, when it comes to their teutonic/templar/sergeants boxes, "I like their minis" - I see what you mean with general business direction.
I'm afraid that they've been biting a little more than they can chew in the last year or so. The fantasy thing is quite huge in their plans and I've heard very mixed opinions about how the miniatures turned out to be and how poorly the whole campaign has been handled so far. Not by bad will I guess, just lack of experience/sources. Don't get me wrong I'm not defending nor accusing them, just trying to be as neutral as I can be.
The ship thing, I REALLY hoped it was a joke. Ok, there are tons of great medieval themed rulesets and minis out there, but in my very humble opinion Deus Vult and Burn and Loot have could benefit if some more love was poured into them instead of dispersing energy in making another whole new game.
Sorry for bad english!
