While not the sole or even probably a significant reason for the decline in split screen; I think split-screen has really suffered because of the need for consoles to be both somewhat affordable but also not terribly behind in terms of horsepower of what PCs can do at the time of the console's release. Depending on the game, the split screen can double the load on the cpu and gpu, and with consoles the way they are now their fps would plummet. A lot of games still are locked in at 30, some 60, which by most PC gamer's standards is already horribly behind. Now of days the vocal crowd of PC gamers say the only way to game is by playing games on 144hz monitors. While I would love to see the return of split screen, I don't think it will with the push to have games be on every platform now and run decently on all those platforms as well.
