Not too sure but i hope not because ***MOST*** people who played split screen in Black ops played Crap as the screen was too small and there is noting worse than a team full of noobs. (My Opinion)
that sucks, i really hated it when the split screen noobs were on my team cause they were so bad! but loved it when they were on the other team cause they usually followed there friend around so an easy 1 2 kill. but i guess this is some what good, a slight improvement from mw2 so when u ever have anyone over ur not having to take turns.
