Unfortunately, Destiny is released before many new releases so people will migrate to other games.
Titanfall had a much better release date, ensuring players no new games for at least 6 months, so they can better immerse themselves into multiplayer matches.
Of course, tastes are individual, but I see myself playing Destiny regularly for many months to come, with weekly playlists, new bounties and challenges, content-packed DLCs, and challenging strikes and raids that deserve to be played repeatedly. Sure, I'll play other games as well, but I doubt many will be as fun as Destiny.
