I really was hoping they would find a way to get rid of the narrow splitscreen when co-op'ing they had in Halo Reach but sadly even Halo 4 still has that narrow splitscreen with two massive bars on its sides. I am lucky I have a big television set but there are plenty of people with small television that suffer from this. It's such a waste of space.

Yeah if I recall correctly it's been a problem with all the HD Halo games starting with 3, which I've played all of them through with splitscreen. I also have a big TV so its not a huge deal but still disappointing.
