NOTE POSSIBLE VERIFED IS NOT A GOOD WORD FOR THIS RIGHT NOW!
Cinderheart and Lionblaze have kits
One of these kits is named Firekit, and is Firestar reincarnated
The other two are named Hollykit and Hawk-kit
Bramblestar and Squirrelflight are mates again( confrimed)
Scourge returns (Highly doubt)
There will be a tornado
Leafpool regains her position as Medicine Cat(Confrimed)
SkyClan will be mentioned
Dumble ( Dove X Bumble ) is cannon
The tornado part is sorta breathtaking see that it will kill many cats.
