If you read the top of the brochure you will see "restaurants will be added as they resign".
Non owned Disney restaurants have until the last of Dec to renew their contract, so you won't know until then, or close to then.
This is not a new question, this time every year people panic that half of Epcot's places are not on there, WPE, etc. You can pretty much say "yes" it will be, as there have only been like 1 or 2 that didn't resign years ago.
Basically they take their time to negoitate the contract. Don't worry, I have no fear WPE won't be listed by next year.
