We aren't remaking Oblivion in Skyrim, we're creating a modern day Cyrodiil, with new NPCs, new questline, new areas, updated cities, etc. we are NOT hurting sales of Oblivion, we are helping keep Skyrim alive with new content. As for keeping track of the projects, The Nirn Project is the site for all the projects together, check it out here: http://nirn.wikidot.com/
