Battlefield 4 is set to be formally announced by EA on March 26, and to hype the reveal, the company put out a teaser trailer today.
The "Prepare for Battle: Sea" trailer showcases a spinning propeller...and that's it, really. Propeller fanatics might find it to be the most enthralling 20 seconds of their day.
The rest of you might be better served to wait until something of substance surfaces.
