I hear he will be there
Im guessing he will be there, if he intends to atleast show a little concern to customers that lost alot of money on his exchange.
I wouldnt be surprised if he gets into some sort of funky situation there, since there are alot of desperate pople who had all of their funds on mt.gox.
I don't understand why people are so fixated on Mark, and wanting to get to talk to him to try to get their coins back.
The unfortunate fact is that the majority of the coins are gone and doing something stupid to Mark is not going to get them back. Mark likely did not personally steal the coins, although his incompetence likely lead to the theft.
Mark had a history of fraud and legal trouble in France, so your blaming "his incompetence" is a bit too kind, imo.
