Given how the story advanced he should have had a 3 iteration that is either a Cygnar partisan or a fully fledged cygnar caster by now, I totally agree.
However, PP have yet to announce anything like that. If they ever do. Maybe during a future Cygnar CID (Storm Knights probably). I noticed they tend to introduce new casters during respective CID cycles. (Anamag with PT, Sorscha with AC, Ione with DH)
My wild, speculative guess is that we see him around the same time we see Ashlynn2.
I'd hazard a further guess that the Infernals disrupt the conflict between Khador and Cygnar to maintain the general status quo between the two nations (then we see Cygnar's first battle engine caster with Magnus piloting his own flying machine for an added dose of complete wishlisting).
