XboxONE full game installs? is a 500G hardrive enough

[SxyxS]

it depends on the user:

I guess the data next gen games will need will rise 3-5 times.
this means:500:3/500:5= if 100-167 gb were enough for you on the 360 than 500 should be enough on the xbox1

if you are a movie fan it would be too small as hdtv movies usually need lots of gb.
