The invisible Cyrodiil borders are not aligned to cell boundaries. They're invisible blocks in the game world that outline the playable area, and they aren't fitted on cell boundaries.
Oops. What I meant was that there weren't any that weren't on the map border, and that's what I was talkiing about. Seems a misinterpretation on my part.
Cyrodiil had a lot of cells you couldn't get to. Besides the cells that were there for show (to give you something to see when looking into Skyrim or Morrowind or wherever), the province has a very irregular shape, which effectively caused Valenwood and Elsweyr to both be in the world, but were completely inaccessible and not even fully viewable without cheating or modding.
Valenwood and Elsweyr are not fully there, see this map. http://www.uesp.net/maps/obmap/obmap.shtml Anyway, they have said multiple times that they are reffering to the "Playable area" and that is also what the estimate of the cell number on the map comes from, not the whole map board, just inside the boundaries of the province.
So, wanting to make things seem impressive is evidence of not being truthful? Take it with a grain of salt, absolutely, but it's not grounds to turn a general "about the same" into a definitive "less".
I never said that. Slightly smaller is roughly the same size, so it's not lying. It's good marketing. And the sort of thing that happens all the time.
EDIT: And why does it take you like half an hour to reply to one post, even when I can see at the bottom that you read it almost immediately after I post it?
