I certainly hope not, there are enough quantity over quality cattle call ayce buffet around, Masa is a very nice sit-down restaurant with top quality food. I would hate if they ruined the atmosphere of there dining experience so people could pile on massive amounts of food just to through away half of it, there's a great buffet on 5th street called "jumbo china buffet" that has decent food a hibachi grill as well as great sushi.
Masa seems like they're going for a quality over quantity, unlikely they would need an AYCE option. Unlikely, but would totally be welcome, in my opinion.
It doesn't look likely.
