Yesterday's video release trailer for the Age of Sigmar was one of the best that Games Workshop has released in some time. In it several models most likely set for future releases were in the images as well as lots of cool artwork.
Here is the latest Age of Sigmar Trailer from where the images were found.
Sent in by Jake, here are some of the images of what look like new models.
These were taken from the video that is currently on GW daily white dwarf.
First photo is an archer unit
Second photo has some character model with griffon welp
Third photo is rending of halberd unit
Fourth is a great sword unit and possibly another hero unit with shield
Hope this helps and there is a lot more for future releases
