Due to the gameplay trailer, I would be confident in saying Helmets, Chest Guards, Greaves, Boots and Vambraces are available are types. No idea if this class as confirmed but you can judge it for yourself.
In opposition of this, the entire armour set is complete possible a single item to complete the look.
There's also the matter of the single pauldron, possibly part of the chest guard however, reviewing the trailer and the official wallpaper featuring the 'warrior' shows the pauldron on opposite shoulders. Just another thing to think about.
Other then that this thread is awesome hope you get a sticky and some more information.
