Some clarifications have come through on what options we will be seeing with a couple of the box sets from rumors earlier today.......... The Forgefiend and the Helldrake.
Once again please note that the pic above is not a GW image or related to the Chaos Helldrake in any form except for being a dragon.
Please remember that these are rumors, however we are getting very very close to the release dates, so bits like this are very certain.

Only comes with one build. Forgefiend has a shooty and a close combat variant in the same box.
Flyer comes with lots of options to build it visually different and aesthetics for particular gods, but it only has one rules loadout.
