Are there going to be large events this year?
Depends on what you mean by "large" - you can view the event schedule here.

Will there be a gen con championship series like previous years with qualifiers available in several formats feeding into championship on Sunday morning? The events posted aren't large by convention standards just numerous.
The only schedule I'm aware of is what is listed in the system currently.
If there are other events you would like to see Pastimes host, I would recommend contact them directly to give them feedback.
