I'm not sure about that. I have watched only two of the Ultimate Pool events, the Colorado Shootout last September and the Boston Shootout this month. For the streamed matches, the Colorado event used a Diamond table with 4" or 4 1/8" corners (per Steve Wyatt), and the Boston event used a Brunswick table with quite generous pockets (but actual dimensions not heard by me). However, it was said that Brunswick is developing a new table for Ultimate Pool's use. One change, I think, will be less slope to the rails, so the chalk doesn't keep falling off. But it's possible that the pocket dimensions could be something different as well. We'll see.
