I have to run out and get a PS4 after seeing Sony's awesome Gamescom show. So many awesome indie and AAA games coming soon. I already own an Xbox One and Wii U, and I feel like every console has so much good going for it right now.
Consoles won't be going away for a LOOOONNGGGGGG time. Even if Sony or Microsoft or Nintendo dropped out of the competiton for some asinine reason, another company would jump right into the competition.
