"Each of us will make our own independent analysis," Robbins said at the Future of College Athletics Summit hosted here by the University of Arizona.
"My prediction is that we're all going to stay together as a Pac-12. There's 10 of us right now. I'm hopeful that the deal is going to be good enough to keep us together."
Robbins said he hasn't recently been in touch with Big 12 commissioner Brett Yormark, but he "continues to talk to everyone" in the realignment space.
He did provide some clarity on any potential move, noting Arizona has the freedom to make a conference move agnostic of what in-state partner Arizona State decides. He cast that notion of a split as unlikely, however, considering his relationship with Arizona State president Michael Crow.
"We don't have to do the same thing," Robbins said. "But President Crow and I are very, very tight. I think it'd be unlikely that we'd be split up."
Pac-12 universities continue to wait for numbers tied to a new TV deal, which is expected "soon," before making decisions concerning possible moves.
