Some have even gone as far to state that the disc inside the tray may be damaged by the system wobbling while in use. No scientific studies have confirmed this:)~
My "brain dropping" on this subject is... Really! Really! Ummm...Really! Make a none issue into an issue.
Fact of matter is the PS4 does wobble if you put force on it. But, who is going to be playing a game and wobbling their PS4. Once you set up your system and place it in you entertainment system your not likely to ever handle it, unless your cleaning or dusting your system or any other console for that manner not Iincluding handhelds of course.
This Wobblegate is comparable to "Tipovergate" for Wii U. Tipovergate is when you apply pressure with your hand to the side of your Wii U when it's placed on vertically and the system tips over.
Tipovergate never existed even though if you did apply pressure to the side of a vertically standing Wii U, Wii, PS3, PS4 it will fall over. Hence the BS with the wobbling PS4 is a ridiculous way to garner website hits for tabloid journalism.
