Actually if someone asked me that i would ask him back, how many clients 4x4 ac capable do you see around?
The 4x4 ac is useless if you dont have any client that is 4x4ac capable.
Aruba i bealive will get in there soon but for now i bealive its not worth it maybe?
Just my 2 cents

Cisco claims that with 4x4:3 they get better coverage with higher speed. They said to achieve max speed (450 mbps per antenna) you need to be closer to the AP then approx. 4-5 meters (1 m = 3,3 feet) given that the AP is mounted in the ceiling at normal height. With their 3700 and 4x4:3 the distance increase to 8-10 meters before connection speed drops. It uses "the extra" antenna to increase the received signal at the client (with beam forming) and the client does not need to be a 4x4:3 client. It only uses 3 spatial streams, so the client would not know.
Would be nice to have some more input on this from Aruba.
