Re: Not really, you're forgetting...
: Xbox One allows 362 gigs of storage (barring any updates) off of the 500gig
: drive, so a 65gig install occupies about a fifth of that if you're
: preloading, but if you were to only get the update, it's closer to 6%.
: Still shouldn't be too much of a problem, assuming you don't download too
: many games.
It won't be 65 gigs. Remember this 20GB is an update, so it's not all content although some of it is.
