How many types of armor are there ?

Yes I know we can change colour and headgear but I was wondering how many types of armor they are in the game, besides N7, Inferno, Assault Terminus Armor, Collectors Armor, Blood Dragon, Cerberus Assault ?  Will there be many more or say just 2 or 3 more ? I am asking because so far only Terminus Assault Armor looks  great to me, and I am wondering about pre-ordering the game because of that.  If there are many more armors in the game, I might decide against it. Also is there a picture of Cerberus Armor ?
