Update (5:05 PM):
Respawn has addressed the concerns stating that Titanfall would only require "20GB on Xbox One". That sounds much better than 40GB.
For those who read about the new Xbox One Titanfall Bundle may have missed the install size for the game running at 40GB, like we did. The PC's install size sits just around 50GB's
In a report by IGN, Microsoft printed "Titanfall Bundle: Titanfall game download card inside marked packages; up to 40 GB required," which many outlets hadn't noticed until now. Keep in mind, games like NBA 2K14 were upwards of 50GB, but the size is making consumers wonder (read: realize) if 500GB's is enough.
This find is right on the heels of a very exciting day for Microsoft as they have recently announced their new Twitch app as well as their new dashboard update to accommodate Titanfall. Titanfall drops on March 11th for Xbox One, Xbox 360, and PC.
