(Thanks @Dragon-Slayer123 for the last fact!)

-It was hinted that SkyClan will eventually be involved with the Clans after the Dark Forest battle. There's further proof of this because Sol mentions a "fifth Clan" while he was fighting Hollyleaf.

-Bramblestar is going to name one of his kits Firekit because he thought of Firestar as a father.

-There are rumors that there will be a book about Spottedleaf!

-The reason Hollyleaf was replaced by Dovewing was because the Erin's didn't know what power to give her.

-The real Jay's Wing chose to be reincarnated into Jayfeather.
