With Fifth Third Buying Comerica, what other mergers are on the horizon?

So it was announced today that Fifth Third is buying Comerica for $10.9 Billion. I think a lot of people have been anticipating some mergers/acquisitions in the banking sector for awhile now. Other than TD, who I believe at this point, legally aren't allowed to make any acquisitions, I wonder if anyone else has any guesses or speculations on what other mergers/acquisitions we might see next? I wonder if a super regional like a US Bank might try to finally come to the east coast? Just curious what people see happening next.
