I guess I'll use this thread for reporting other new and possibly useful stuff I find from this game.
I've tested Operation: Swordbreaker pretty thoroughly now, and despite the new OoBs, I couldn't find new sequence breaks. One theoretical skip would be to go OoB and underneath floor after passing through the big temple, and then hit the vent trigger of the underground passage from OoB. This would skip the conversation with the wounded soldier. However, the ground is too low in this area and it looks like the underground passage can't be reached from OoB.
This also happened on one of my replays of the level. Might be a time save if it was figured out properly. (Video description has most of the info.)
