@angelsx: A while back, a Chinese forum leaked information about BF4 and End Game. They got it right with the Air Superiority coming back to this DLC. You can find more info here -> http://n4g.com/news/1114116...
I am sure there will be a big player base after BF4 comes out but if you haven't got the Premium Pass yet it's a little scary to this late. If it was cheaper than $50 still maybe I would even consider it...
