Earlier today, DICE started to blow the lid off of what we can expect to see in Battlefield 4: Final Stand. In fact, starting today, they're making the Final Stand maps available in the Community Test Environment.

Hell, even beyond that, DICE even mentions Battlefield 2142 in their latest news post about Final Stand.

This is how the map testing on the CTE will work. Starting today, DICE will run servers with one new map per day. Player slots will obviously be limited on those servers, so just because you're in the CTE, it doesn't mean you'll be able to play these maps.

Beyond that, DICE also released the first actual trailer for Final Stand.
