Sorry about that. I keep checking the usual places, too.
No, I'm not sure where to put it. It's one of those things that's probably mostly an anime spoiler but could also be a manga spoiler... and a healthy dose of speculation. It's all based on the episode descriptions for the upcoming anime eps. (And the grainiest photo ever.) There was a healthy discussion about it already on 2chan and a JP blog (which copied the 2chan discussion before the thread died.)
If Saki had its own sub-forum, I'd know exactly where to put this. As it stands... I have no idea.
