It looks like the Explore Equestria site has updated with another location (as far as I know, the updates come so infrequently I can't quite remember), this time looking at Cloudsdale! As usual it looks like there isn't anything new or substantial hidden in the page, at least from my cursory digging, other than little factoids, videos, and such.
