4v4?

Will there ever be a 4v4 map? I find that a lot of people really don't like the 3s map, at least not my friends. On top of that, it is a bit difficult for me to have 5 friends of about the same skill level on at one time, or even 5 friends that all like each other enough to play with voice chat. I know one less person isn't a huge difference, but i for one would like to see another map with actual competitive potential.
