SUPERFOX5

I’m depressed as well about not being able to see the Mane Six again.  I’m trying to go in with an open mind but the premise that we have so far is making me scared. 
I hope to my dying day that we don’t let go of these ponies...

Nothing will ever take G4 away from us. It's been released and its show completed. Hasbro can't take it back even if they wanted to. It earned its place in internet and cartoon history, and it'll have a special place in my heart forever. I imagine MLPF will be a home for it forever too. Even if we end up being super "into" G5 as a site, I expect we won't forget about our G4 roots and we'll aim to make it fun for fans of both to coexist here in the name of love for fantastical sapient equines in general. If you don't end up liking G5, perhaps it would help to think of it as a really ambitious fanfiction that you might see a lot of (think Fallout: Equestria), not particularly care for yourself, but with whose fans you'll still be able to enjoy the concept of pony with?

I've been mentally treating G5 as a continuation of G4 with a long timeskip in between. To me, that makes it emotionally feel like the excitement of a new episode or season that we know is coming. I have reason to believe that Hasbro's creative teams are putting in an A effort to build on what made G4 successful while respectfully giving closure to G4. As bittersweet as the end of official G4 content is, if there's any silver lining to it, it's that they can't ruin it either. We can see the Mane6 again any time we want by rewatching FiM or exploring everything its fandom created - and continues to create!! - until the end of time. Nothing can take them away from us.

The best possible outcome I see is that instead of having just one grand pony saga to love, we'll have two! G1-G3 notwithstanding - I'm talking about those of us who became MLP fans through G4 and didn't get hooked by the earlier generations. Add to your "grand pony sagas to love" count accordingly if you're a fan of those gens too.

I know what you feel, I can relate. I think I'll always prefer G4 myself, or at least I'm not planning to change that priority anytime soon. It kinda feels bad, that the G5 will be "stealing" its spotlight, so to speak, especially considering that I'm still working on G4 fan content.

If the banner has added to your concern, I'm pretty sure it may be cycling between G4 and G5 ones, or at least I'd suggest so. I don't think G4 will be swept under the rug, it plays the biggest role after all.
