I heard that the new TES game could also come out on the wii...although nothing is for sure yet, i really dont think thats a good idea.
Not gonna happen. Whoever told you that is wrong, so this thread is not needed and can be locked. No point in letting false rumors spread.
Wont it be a butchered version with the graphics of a PlayStation One and, a smaller world?
If a TES game was released for the Wii, it would probably look like Morrowind. The Wii and the original Xbox have about the same power. So no, not PS1 graphics and not necessarily smaller.
