I don't think Andy is playing anything til that Kooyong exhibition. but nothing has been officially announced from his camp about next year's schedule. The only tournaments we know he's playing are where the tournament has announced (Scottsdale, Memphis, Houston, etc.).
Plus, playing in Doha is NOT the *only* way he can stay #1. If Andy were to do better than Roger at the AO he would still stay #1 and I mean it'll be the start of the season, we have no clue how either of them will do. And I don't think Andy will do anything out of the ordinary to keep his #1 (such as playing a tournament he wouldn't normally play), and nor should he, he should just play the best he can and try to make it to the same level or even further than the previous year
