I see the College of Cardinals has stated that all of the “voting age” cardinals will participate in the conclave. If you’re keeping score, that’s 135 or so despite a cap on 120 being formally in place for some time. Although Popes have exceeded the number of Cardinal electors in the college many times since the 1970’s, there has never been a time when more than 117 I’ve been alive for a conclave. 
Archbishop Vigano raises this point here:
“He also said, “the Apostolic Constitution Universi Dominici Gregis that regulates the Conclave, confirmed by the Motu Proprio of Benedict XVI Normas Nonnullas, peremptorily establishes that the number of Cardinal electors must not exceed 120 individuals. But the Cardinal electors who make up the imminent “conclave” are 136: we are therefore faced with a very serious violation that alone would be enough to undermine the legitimacy of any supposedly valid Conclave.”
What to make of this…
