I want it. I need it. I really like her mane!

First pony that came to mind not considering it had to be the Mane6: Trixie. For reasons already mentioned above. +2 insightful and probably spot on!

Your not asking the correct questions, or at least not specific enough. But let me try several versions. - Will the movie attract new bronies? Probably not. Reason being most non-bronies wouldn't go to a MLP movie. Why would they? It's a movie intended for little girls, not adults. The reason we have bronies now is that most were able to watch this in private at home, not in a big hall with lot's of little girls, which is what most people probably will think of what will be there in a MLP movie in the cinema. - Will the movie cause the return of ex-bronies (I guess mostly anti-twilicorn fans) This is more probable. But I don't think it will be a huge increase in active bronies. Also because this movie will most likely feature twilicorn, which was the reason a lot of bronies quit in the first place. Also: did the brony fandom leave in the first place? I don't think so (look at the people still attending this board, Equestria Daily or any MLP convention). At the most there has been a slight decrease in the total number of fans still watching the show. Regarding if season 7 and the EqG series next year will be any good: only time will tell. Noone can properly give an honest answer to that one just yet. The show's staff will ofcourse try to make it good. I don't think it will be bad, but then again: what is good? Compared to what? I think season 5 had a peak in properly good episodes, but they had very good occasions to do so: 5 years of MLP and 100 episodes are some big landmarks for a show. They also had a couple of story arcs which lasted for some years come to a conclusion. It's very hard to top that. I enjoyed season 6 less than season 5 because of that, but I still think season 6 had some pretty enjoyable episodes. The same can probably be said for Equestria Girls.

Quoted for truth! Oh, disregard the signature on this one.

To quote a known person in the community:

Give Celestia some more backstory/character building with her very own episode

According to wikipedia, there were over 1 million viewers for the Canterlot Wedding episode in the USA alone. Not all of the viewers will be considered fans, but on the other hand, I guess not all fans watch the show in a legal manner (either unable or unwilling). Globally an estimate between 1 to 10 million fans seems reasonable, and I'd say it will be to the upper part of that 10 million, maybe even a bit more.

/me joins the fanclub Luna is best pony! And how can you say no to such a plushie?

I believe the brony documentary from de Lancie/Faust/Strong (2012) stated that most bronies (attending the conventions) were in the age group of 18-25, with still a decent amount reaching up to 35, and also children and teenagers running around. Now I realise convention-goers aren't neccessarily the average brony, but I would guess the ages won't differ much. I'd say most fans (non-target demographic) nowadays would be 16-30 with the bulk still in the 20-25 range. Personally I was late to start watching the show (summer 2015), and relatively old with 34 at that time. 2 collegues of mine, who've been watching the show for a longer period, are 30 and 23 right now.

Above all I would like a Celestia-centered episode. And I say this when Luna is my waifu and best pony: she's had quite some episodes where she had at least an important role and at least 2 episodes centered around her, where Celestia nearly never really had any role of significance or backstory. I was saddened when I read that Larson had written some backstory for her in Amending Fences, but it had been axed due to time limits of the episode. Because of this I particularly liked the comic where Celestia goes on an adventure with Spike alone. Maybe a story similar to that might work in the show as well. Here's hoping for season 7 to right this wrong.

Likewise, I binge-watched the entire show in august/september 2015 and didn't read into any of the meme's, fanfictions or other stuff at the time. Thought it was a funny episode, until a little later I started watching ACRaceBest's Bronies React video's. That threw me into the rabbit-hole that is this fandom which in turn made me realise how important this episode was to the fandom and what it *actually* was all about. I love looking up react-video's to this episode to see how this impacted bronies all around the globe, now knowing what all the references and memes were about, and how nearly every reactor completely shuts up during Gummy's monologue.
