Harrah's announced the schedule for the 2007 WSOP today:
There are 55 bracelets up for grabs this year.
If you want to play in all the events - and don't rebuy! - it's going to cost you over $200k.
There are a total of 25 events hat cost $1500 or less to enter.
I see that 13 of the events are considered "World Championship" Events, but I think you still get a bracelet for all the other events. It looks like they don't have any events running during the Main Event though (and I am sure they will) - so they will probably treat those as non-bracelet add-on events. Just my guess.
The WSOP kicks off on June 1, and the Main Event (with three Day 1 flights) begins on July 6th.
Mark your calendars.
