MW74 will not end early.
As for the call to END MW early, that is not going to happen. For one, people who have since deleted have forfeited their voice to influence the round for those who are still playing. It will not be a good precedent to set if we show players that they can mass delete from a round to force an early end.
That aside, even if all current players did want to end it early, it would disrupt our code release cycle, which is planned to see the next set of changes go out on March 09.
Even if everybody deletes right now, MW75 will not start until the next code release. MW74 will end on March 4, as planned.
