Crysis posted a tweet today saying there will be a major announcement tomorrow saying..

As Nomad once put it: "We're going Back"

Looking forward too it, working on a commentary for yell with some info.

I'll be buying the map pack day one and reviewing it for you guys. I'll post footage of each map as well as tips and tricks for the new weapons.

Probably DLC

If it was DLC, it isn't really major at all considering the low population count.
