Local multi is... I dunno... kinda 1995. Sure, it has its uses and some will like, but the world has moved on to online play. No one is saying that they have one at the expense of the other, but I don't see this as a driving feature.
Local multi didn't die cause people don't like it. It died cause it wasn't possible anymore with modern gaming. Split screens are lame.
If people could have their own console and play call of with friends anywhere with 4 screens ? That's entirely different.
