This initial Revan sure looks to be LS if Bastilla, Jolee, Mission, Zaalbar, and T3 are required. If these characters were to help him along a Hero's journey it would look to be a redeemed version of Revan along the cannon lines.
Later on they could actually release DS characters and do a separate DS Revan - they wouldnt have to be companions even- just DS characters who helped the player chose DS options while playing the game.. Canderous, Malak, Bendak Starkiller, a dark Juhani
Obviously a light side Jedi is needed more for game balance, that will happen first
