I don't even know why you would even ask that question. The answer is YES we all will still be fans. Like many people have said in this post the show will continue to live on in many of our hearts. You just can't erase what every pony artist, Blogger, Musician, animator, etc have done. People will still continue to enjoy the show specially because I feel like the fandom is too big to be erased. I mean look at many old shows and its fandoms and you'll see that they are still there. Many years from now when I have children I will still show them the show and I am guessing many of the fan base will do the same.
