It certainly could. But I think they are also a bit different.
TitanFall being an always online group game may bring more people to online FPS play. But we have yet to see how much of a story it will have. It will certainly capture the online FPS market. But for how long?
Halo had a great story, and lore. That in itself makes it a rather remarkable experience. There are many that play Halo just for the single campaign. Or the campaign with other people either local or online. Then you also have the online battle play and maps. Halo has more different ways to play for more different kinds of players.
