I'm so glad I'm not a teenager these days or being a parent to one. Damn kids would want every console that came out, every game, every controller, every accessory.
No thanks.
I even regret buying my PS3, but it comes in handy for watching things off of a USB device. Not buying any consoles ever again. Waste.
Two of my friends are hardcore gamers swear not to get the PS4 because of the lack of backwards compatibility. Don't blame them one bit.
I would image Sony could easily make it backwards compatible, but capitalism dictates otherwise.
