This was interested me as I was wondering how long it would take a 30+ gig game to install on the next gen consoles to the point that it would be playable while the install run in the background. Considering the install of Skyrim recently of 4 gig on my PS3 took about 15 min, I think even 9min on the Xbox One is reasonable but the PS4 times are impressive.
