That's all well and good that there might be some new content in 7.0 (Summer). But what about AFTER that update? Will you be continuously adding new maps, vehicles and/or weapons, or is that "it" ? Are we to assume new content of any kind will end with 7.0? Bug fixes and balance changes is not "content". Maps, Vehicles, Weapons ARE.
It's stated in the blog that the June Update (7.0) will be the last content drop and we'll have those details once we get Update 6.6 out the door.
