When the 360 came out, I all but quit PC gaming between 2006-2011.
Since 2011 my gaming has shifter primarily to PC.
It seems PC will be my platform of choice this generation, with a PS4 thrown in after a couple price cuts.
It really helps that pretty much all exclusive 360 franchises I follow kind of completed their important sagas (halo 1-3+reach, gears 1-3, etc.).
So yeah, PC + (probably) PS4 for me, after two generations with XBOX and 360. And I still love my launch 360.
