PlayStation 4 sell through in the US has surpassed 30 million

[VAMatt]

I'd really like to know what percentage of US households own a PS4.

I'd also like to know how many of those PS4s are actively used (say, how many have been turned on at least 10 times in the last 3 months, or something like that.)

I'd also like to know those same stats for every system.
