With courtesy of Nitnendaan we have now some nice direct-feed screenshots of Zelda BoTW on Switch. There's a spoiler warning because one boss unrevealed in the trailers (but revealed in the GameInformer coverage) is there, I'll post it as a direct link to the screenshot, so you can browse without getting spoiled.
