I would at least presume there's fighting on land, but two new trailers have DICE confirming, or at the very least teasing, some of the their future first-person shooter's battle environements. The trailers are both succinct in their respective entirety, but it should be more than enough to get your noob pwnage blood flowing.
Air combat finally made a triumphant return (sort of) with "Battlefield 3's" final DLC, End Game. I'm excited to see what they'll have in store for the not-so-friendly skies with the new game, especially with it hitting next-gen consoles.
However, I'm more excited to see what's going on with naval battles. I really like the idea of going Red October on an opponent in a submarine. Likewise, being inside and under water also adds some claustraphobia, which is a great avenue for the new "Battlefield" to explore. Actually, I'd just like to be able to hear someone say "Damn...you sunk my battleship," without supporting those money grubbers over at Milton Bradley.
DICE has March 26th earmarked to reveal more details about "Battlefield 4." We'll be sure to tell you everything.
