We’re fully expecting Apple to announce the Apple Watch 4 later today, but the company appears to have slightly jumped the gun, as its sitemap files were seemingly updated to include links to the unannounced wearable in 40mm and 44mm sizes.

The links don’t work and the sitemap list has been removed, but not before AllThingsHow took a screenshot and downloaded the sitemap.
