...It only takes 1 move people haven't seen yet to change all that jazz
One move that's only a little bit slower and longer range than 1K? I doubt he has one. Right now there's pretty well defined line where the range of his moves end, seems to be a pattern. He's just a short range character. It's true that one move could change things, though, but let me explain all this jazz as you call it.
The way I see his move list, there are three distinct spacings which must be played differently. The first is up to his AA, 6B, 2A, and throw range, where he has access to fast, safe step killers, his fast mid 6B, and his throws. Beyond that range, up to his 1K range, he has his mid horizontals, B, 236B, and some other tools whose ranges all seem to end in about the same place. After that he has some really slow moves... basically, you can react to any movement and block anything he throws at you outside of that 1K range, based on what we've seen so far.
There's sorta also a important distance in between the first two where BB won't whiff after the first hit, and he has access to 66B and the toe stab.
In general, key spacings or zones to consider are places where reliable step-killing moves are in range, where mid-low mixups are in range, and where fast enough attacks to hit people before they react are in range. Patroklos's step-killing and mixup seems to have an above average range but that third area is very short. Also, the line between his reactable moves and his nonreactable moves is especially distinct, kinda like SCIV Yoshimitsu.
In my opinion, this aspect of a character the most important thing to consider when learning how to use or fight the character. All matchup knowledge should come from this, it tells you where to stand for best r/r and what options are available outside of situations where players are attacking immediately out of hit/stun/recovery (frame data is what tells you everything in those situations).
So yeah, right now I'm just speculating on his effective spacings, it's gotta be the most comprehensive way of conceiving the implications of each character's toolbox... I like to think it's important to talk about :)
