The biggest threat to Nintendo is the lack of software releases - so far.
Lack of software releases will continue to grow as companies move from supporting PS3/360 to PS4/Xbone. The Wii U will start missing out on some of the best games of this upcoming generation because its hardware is in between generations. The Wii atleast had sale numbers behind it while Wii U sales are bad and the PS4 and Xbone sales will probably surpass lifetime Wii U sometime next year.
The PS4 wobble reminds me of that old joke.
Guy goes to the doctor and tells his doctor: "it hurts every time I touch myself here." The doctor replies: "Well then stop touching yourself there"
If you don't want the PS4 to wobble then don't push down on it. The system is motionless when you don't touch it.
"to comply with the law, to protect our rights and those of our licensors and users, and to protect the personal safety of our employees and users"
That is the important part of that text. Basically if you are going to do something illegal over PSN then Sony is saying they have the right to turn over that information to the correct authorities.
It is simply to protect their butts.
