Chess at 3 with Wesley So, 4pm-6pm EST

>> will he become a regular player here?

I am sure he won't. All those top GM's aren't interested to play without money. Lichess definitely has a lot of strong players, but typically those players are youtubers (or streamers) interested in big audience - very important source of income for them. And the very top players are interested in competition, not in audience.
Lichess is a site for recreational players, because of great QoS and great functionality.

I doubt it, in the stream he said something like "I don't play bullet, only blitz occasionally". He'd never heard of lichess, but was positive about it.

We can expect more strong titled players to come to lichess gradually (perhaps anonymously), as the momentum turns from chess.com. But currently, there isn't the level here to give them a worthwhile challenge.

He does not play bullet? Hmmm... but at least Death Matches for money...
