Will anniversary have avatar awards? I don’t know how to ask bs angel a question, so if you do know how can you either tell me or ask it for me?
I don’t think so. All I know of is the Master Chief costume you can get for your avatar if you preorder Anniversary.
I hope it does those were fun to get in reach and odst and waypoint, but i don’t think any avatar thing will stop me from wearing my master chief pre order armor 
Master Chief armour is the only one (for now)
Since 343i put some in Waypoint, I don’t see why they wouldn’t put some in CEA. We’ll have to wait and see, I guess.
halo ring prop, sentinel, reach marine armor, marine helments, health pack, flood body, elite armor, arbiter armor, Halo CEA mark V helment, grunts, jackels, pet MOA, and everything between ten years of halo
