Fans will start rioting the streets, flipping cars, smashing windows, but it will get worse. Panic will spread through the world, and...... this is what is not going to happen.
The fandom will live on, as everyone else is also saying. I mean, look at us now, drawing art and writing stories, and the next season isn't even out yet. It will be pretty much the same as it is at this moment. Don't worry, with all the money Hasbro is making from FiM, it won't end anytime soon.
