Bethesda may be working on an unannounced game that could be revealed soon. Listings to that effect have already appeared on Amazon.
There, an unspecified title is listed as 'Placeholder T03, S02, and E01,' each representing a standard version, a deluxe edition, and a collector's edition, respectively. Bethesda is listed as the publisher, with a potential release this year. Furthermore, the title appears to be planned for PS4, Xbox One, and PC.
Unfortunately, no further information can be found in the Amazon listing; however, a short teaser is attached, featuring an old-school countdown.
It's possible the entries refer to The Elder Scrolls VI or Starfield, although these two games are currently expected to be released in the next generation. Beyond that, there's speculation about a Fallout 3 remaster or an entirely new IP. So, for now, we'll just have to wait and see what's really behind it.
