What capability is required to view posts, scheduled in the future, by someone else?

I found Future posts are not exactly a different capability.

In WordPress Roles and Capabilities I found edit_others_posts is available by default for Super Admin, Administrator and Editor. I think it will be a right way you can proceed. (Not tested though)

And additionally try with edit_published_posts, publish_posts etc.
