As the construction permits for all the changes are filed, TVFool.com can incorporate them into their database.
There's already an option on the TVFool.com reports to view either current or pending applications. That option will be perfect for choosing between how things stand now and how they'll look after everyone has moved.
That said, it's not uncommon for TVFool to make mistakes. I suspect their message boards will be quite busy with notices that "no, station WXYZ hasn't moved to their new channel yet" and the like.
