Well, maybe if Harry Reid didn't mention it as something they were going to do if they held the Senate it wouldn't have been done. One thing you have to know about McConnell, he isn't going to do something unless there is a precedent to do it. If Reid doesn't jump the shark and shuts his mouth it probably wouldn't happen. Now Schumer is talking about killing the filibuster. Why wait for the ones with the ideas to actually do it?
