In that case, yes, they'll definitely do the 75th anni.
Wow this is pretty interesting stuff... So when they did the 25th anni. most players are different from the 50th, so this should mean that when they do the 75th they will change the 50th around...
I would think they would have kept the 25 players the way it was and then on the 50th just add another 25 players and so on. Too much confusion if you ask me, but let's see how things go on the 75th.
