Hello!
The information about this event is quite few, I'm still not sure, is this event going to happen?
Is the event's program going to be published somewhere?

I also curious is there kinda web ticket that lets watch whole event on youtube or something like that?

I would say keep checking YouTube for videos being posted, SideFX is usually pretty good with that:
