Deepstriking onto the radar is a new box I wouldn't have called from way of of left field. Chaos Daemons now have a battalion (battleforce) to help get those daemonic players a start. It seems to come with a whole host of daemons representing all of the dark gods but Nurgle. Must be too nice to put resin in a big box :P. And it's not too bad if you are looking to get a host of daemons for an undivided army. That said, those who favor one or two gods may do better to simply buys their units alone.
A few new toys did come into play though. A Finecast herald of Tzeench on disk being the main focus and some very pretty resin banners.
I was pleasantly surprised to see some of the Archon's command squad units finally have some models.
