Duke, Miami, Syracuse, and Louisville
And then there were 4 (current or future ACC members) remaining.
The Big East showing in the tournament has been a disaster other than Louisville and Syracuse who have both looked very strong. The road does not get much easier for any of these four teams. Louisville and Miami both have legitimate chances to make it to the Elite 8 but it is possible that no current or future ACC member makes the Final Four. Louisville has the best chance against Oregon and Miami should be able to hold off a tough Marquette squad. However, Duke and Syracuse both have tough games against Michigan State and Indiana respectively. Having been at the 1987 championship game to watch Keith Smart’s shot sail over Howard Triche’s outstretched arm, the ball fall through the hoop, and then inexplicably NOBODY call timeout – there is nothing more I would enjoy seeing then Syracuse knocking Indiana out of the tournament. If Howard Triche’s nephew, Brandon, can hit the winning shot – that would be even better! It was a torturous ride home from New Orleans to Syracuse after that one.
One way to guarantee current/future ACC representation in the Final Four would be for all four teams to win this round, which would then guarantee two teams in the Final Four, and then we would have a Louisville-Duke matchup and a Syracuse-Miami matchup. Those would both be great games with some conference bragging rights on the line. Let’s hope it happens!
The Confidential 
You left out the best possibility – an all-ACC (current amd/or future) championship is still possible
Good point! Living the torturous life of Syracuse early exits always has me with the glass half empty.
Louisville and Syracuse for round #4?!
Round 4 would be crazy! After the collapse at the Garden the Orange would be terrified of a fourth game!
Syracuse is a great team! Their size scare me at the guard positions. If Williams, Trich and/or Sutherland get hot they can beat anyone. Good luck Cuse.
