Seriously, lots of extremely vague stuff going on here. Going through the post, though:
OK, sure, a Khorne battletome for AoS, I guess AoS Khorne people will be excited about that.
Some kind of... game? Called Warcry? Designed by the teams who did Shadespire and Kill Team, so that's good, but that's literally all we know aside from "it's in the AoS Mortal Realms".
The tree elves warband for Shadespire, which is extremely beautiful and rockets right up to the top of the queue for my "Shadespire warbands I want" list.

Shadowspear, the next battle box set for 40K, with Marines and Black Legion, but with all new models for both factions, which is a new (and cool) development. Looks like for-real Scout-type Primaris marines (sneaky, as opposed to the shock/terror troops that Reivers are), with camo cloaks and sniper rifles (and a camo cloaked Librarian), new Chaos Marine sculpts, new Obliterator sculpts, and a cool new spidery daemon engine.

A new Sisters of Battle image, which looks like a Sister of Battle, but that's OK.
And finally a teaser trailer for the new Abaddon sculpt, which is apparently getting released in early March.
