Which will sell more Killzone Shadowfall or Titanfall (on XBOX ONE)?

[sth88]

Tough call. Killzone has the advantage of being an established franchise, but it's never been a mega-seller. Titanfall, on the other hand, is a new IP, but the buzz around it at E3 and Gamescom indicates that it has the potential to sell BIG.

In short, I don't know.
