Nobody has an update on @TMAN yet. I think @Lauda would have had some idea. Then again, those two really were part of the old guard so its possible that they didn't have any idea of each other's real world identities.
I'm not quite clear what you mean by Lauda's idea
I think amishmanish thinks Lauda and TMAN knew each other's identities, but I find that unlikely. Lauda was extremely private, and as far as I know never gave clues to his/her identity--but if anyone would know it, it would probably be Theymos.
p.s. And as I understand by "old guard" you mean adherents of crypto-anarchism?
I don't want to speak for amishmanish again, but I'm pretty sure by "old guard" he means long-time members of bitcointalk. Amishmanish registered in 2017, so both Lauda and TMAN probably seem like they've been around since the beginning, even though they both registered in April 2013 (4 days apart, which I never realized....hmmm). Come to think of it, they might know each others' identities quite well.
