Some info on those Star Destroyers (from people taking a close look at them from the teaser):

Spoiler!

Folks have pointed out that they appear to be Imperial Star Destroyer I's, the original version from A New Hope. Perhaps stashed away by Palpatine.

Others have pointed out that a few appear to have a very big looking turret on their starboard side, which could be the source of that orbital blast we see hitting the surface in the teaser. So even if they are all ISD I's some have clearly been upgraded.
