im putting my money on they add in a copy of the tower next to the tower...or maybe a secret location on earth with just 2 towers on a plain, with enemies fighting, and loads of loot, with special event liveries and such. (i.e a sniper or something with the words "never forget" on them.) or you know, have some sort of minute of silence in the tower, or hour of peace where NOTHING attacks you, you can collect loot, but not complete missions. (is crossing fingers on the tower with loot thing...because i would totally play the shit out of that location for a day. if im gonna get crazy loot for it...) but i still wonder what they WOULD do on that day. who knows?
