GoNintendo has just posted a huge list of media assets from the Nintendo Direct. That includes a ton of new Star Fox Zero images. There's pictures of the team, closeups of the new vehicles and modes, and, curiously, what look like ship textures and user interface textures used on the website. This in addition to a lot of images we've previously seen, but in different resolutions.
I say 'different' because the images are highly compressed, more so that we typically see. They look blockier than they ought to, even on the original versions of each image. However, this could have been an upload mistake somewhere along the line (either Nintendo or someone else). I'm looking into it. Update: They were compressed this way by Nintendo themselves. :(
See the Flickr Image Set for all the images.
