There's no guarantee all these stations will be allowed to go through with the transition early. The rule changes that go along with the new transition date allow the FCC to force stations to wait until June 12 if commissioners feel it would be "contrary to the public interest" for them to switch over early.
It seems likely the FCC won't allow that many stations to switch this month. That raises the question of whether there may be lawsuits by broadcasters who are stuck with additional expenses stemming directly from the Federal Government's sudden change of plans.
