While working out last night in the gym I pondered the itch that Marcus needs scratched. Marcus can be a real cheap son-of-a-gun at times... Wants everything for free.

I have however "teased" minds with what I say are parallels in this form, the "Big Three" forms, and the bridge kata. It is a fascinating piece of work.
Imagine knowing only Sanchin and Seisan, and you heard that there was another form Kanbun knew and never taught. Someone comes back from Fuzhou and has this Sanseiryu form. You learn it. Would YOU be able to tell that this form belonged with Sanchin and Seisan? I know I would have a tough time of it with only two data points to extrapolate from. Most I believe would reject Sanseiryu as belonging to Sanchin and Seisan. It truly is a different animal.
It's a LITTLE easier having seen three (instead of two) forms in a sequence, and then guessing if a fourth belongs there somewhere either as a missing piece in a package or perhaps some distant but highly relevant cousin. It's easier still if you've done some forms from other cousin styles (like Wing Chun) and are qualifed to teach in a related Naha system (like Goju Ryu). That's my perspective.
What might make some interesting piecemeal clips and/or a full DVD would be some comparative analysis. I talk about sequences on these threads, but it's hard to picture them. It's easier if you see them being done first in Form A and then in Form B.
Let me think about this a bit...
Yea, I do get around to some things now and then.
