EQG is the reason we have to wait a year for season 4. There are plenty more reasons to be skeptical of it, but I think that that is the one the fandom should be able to agree on.

Also, like AugustDay said, if it bombs, what are the odds that Hasbro will do a REAL FiM movie? Pretty slim I should think. If EQG sucks, there’s a good chance that it will be unsuccessful. If it’s unsuccessful, that makes Hasbro less confident in the brand. If Hasbro is less confident in the brand, they are more likely to micromanage it for damage control, and I’m pretty sure we don’t want that.

Really, who keeps saying EQG will ruin the main show? I've never seen anyone say that, honestly.
