A post on
RPGDot that
references a magazine ad that's also mentioned on the
Gone Gold Forums, seems to confirm that Bethesda Softworks has plans to announce Tribunal, a Morrowind add-on due November this year. According to the update,
which speculates this will be officially announced this week, the expansion will
add a couple of new cities, some new monsters, and "epic sized
dungeons." Thanks
