I don't know if anyone has touched on this issue or not yet. And honestly I can't be bothered to do four years of back reading.. but portable gaming has in recent times got it's ass handed to it by mobile gaming.. what is so unique and wonderful about a 3DS of a P's vita in times when 90 percent of the gaming community has a smartphone.. seriously. I realize the vita has better specs then say a Sony xpera. But when you consider that someone's smartphone also plays really high quality games and some smart phones have built in controllers. Plus do the net plus text and make phone calls. While also looking ten times more acceptable to play publicly because people think it's just a phone.
People don't want to look like a goofus publicly. And smart phones do so much that portable gaming devices just can't hold a candle to the style and practicality of a good smartphone..
The day of the huge portable gaming device is almost over.. Nintendo would be smart to consider making their next portable a functional moble smartphone .. like sony did with the xperia play...
I feed off your fears
