So here's my list of the five most likely outcomes:
1.) The perp confesses to everything and takes credit for working for three years to inflict harm on a young man in the public eye. He does this in a 1-on-1 interview with Deadspin or some other non-traditional media organization and cashes in on his 30 seconds of infamy. I put the probability at 40%.
I assign this high of a probability because there are several plausible factors that might force this option. First, if this was indeed a catfisher, if they do not reveal themselves then they do not get the glory. For a sociopath, that would take all of the gloryhole out of it. Second, CAA and Manti's lawyers may be putting the squeeze on them. Third, if it's just some jackhole living in his Dad's basement, then he will probably cave under the sign of pressure.
2.) The perp confesses but claims Manti is a willing co-conspirator. This statement will also likely be made to Deadspin or their ilk. I put this probability at 15%.
If the perp drags Te'o into it (rightly or wrongly), he's denying himself credit for pulling off a great (from his/her point of view) scam. However, the one thing catfisher/sociopaths love more than attention is ....ing people off.
3.) Manti's lawyers and CAA are waiting for the perp to make a move before saying anything because they've got a truckload of evidence on their side. So, they are waiting for this perp to come out with something hoping to swoop in, do a massive document drop to several outlets and completely discredit whoever is behind this. I assign a probability of 20%.
4.) Manti lied about everything and is in sociopathic cahoots with the bad guys. CAA knows this and is hoping that the other perp won't down him. Or, they have bought silence. Since he has zero documented problems in his history with authority, I assign a probability of 5%.
5.) There was an attempt to extort Manti in the last few weeks and law enforcement is now involved. I am envisioning federal grand jury, so the whole thing is sealed, and he was advised not to speak on the matter until an indictment is handed down. I assign a probability of 20%.
