Anyway, due to his appearance in the old files, I'd bet that Oculus is in. As a second, I'd like that crystaline guy. Kestrel used his concept art as an avatar for a while. Looks like there might be some kind of stealth gameplay going on there

the falconess is a general, back when the concept arts where still in the imagename had the same formatting as all other generals. For example HESA = Hero Good Sniper Assassin = Regulus ; HEMA = Hero Evil Mage Assassin = Torchbearer ; The Falconess had definitely a G in the end as did Oak, Oculus, Sedna, Erebus and QoT.
Interesting.
Speculation: The four not included so far are divided between Light and Dark, and include one Assassin and one General for each side. Falconess and Occulus are Generals, but for which side? Yoshimitsu looks Dark, which makes Crystalline Light Assassin?
