Its been a regular on DDP for several years. As stated Disney's list is not complete until later in the year. Happens every year before all restaurants are listed.
That said I can't recommend Teppan Edo. It's well rated but seems to be liked by those who do not have a Teppanyaki restaurant in their home town. We found it is way behind compared to what we have at home. Even worldwide chain Benihanas is far superior. But, if you don't have such choices Teppan Edo is fun and has decent food.
