So it was based on 5 of the top games recently? so... I'm guessing that rules out the Nintendo Network since it would be 3rd party games on both X1/PS4 also... could look at a sign of volume of players using an online service, I mean there is complaints of queue times/latency and such now in WoW because of the expansion launch and people playing it, Very few complaints about those things for the last 12 months while the player numbers were down.
I'm just saying if they are taking a sample of satisfaction from a direct number of complaints about either service you would have to divide that figure by 2 before even starting to look at how much the extra amount of people using psn over xbl would effect the service. I mean you could run the most enjoyable bus service in the world if you had a bus with one person on it, they'd have the time of their lives compared to a bus full of people, doesn't mean the full bus is in trouble though.
