Yes. Most anticipated release right now alongside Fireworks.
Edit: Might not be a teaser for a full length. The website is still decked out in Wildlife stuff, and I'd expect them to make a completely new website teaser and make it a big thing. Might be a new song or an EP. Maybe Here, Hear 4?
The timing's right for a new album, but with the countdown being for nearly a month they might be leaving the wildlife set up on there to keep more guesses going instead of having people infer that it's a new album.
