So I'm guessing this will give us an idea that it would be called "The Elder Scrolls V: Skyrim"?
Possibly. Also, http://www.gamesas.com/index.php?/topic/1100625-tes-v-speculation-thread-42/
We don't
know that they'll make a new Elder Scrolls, but we're all about 98% sure on average that they will. They've said they certainly will, so if they don't, it's because they're going bust, and not because they're dropping the IP altogether (since it's their single biggest income). And yeah, they're not going bust anytime soon, so you can almost certainly expect a new Elder Scrolls in a few years.
But yeps, go to the speculation thread instead.
