I doubt that.
What I really wish they would do is drop the whole TES # crap, Reboot The Elder Scrolls in the post Skyrim era. Just call it "The Elder Scrolls". Start with whatever province they may use for TES VI and and whatever storyline they have in the works.
So if it is going to be in Hammerfell, don't call it "The Elder Scrolls VI: Hammerfell." Just call it "The Elder Scrolls: Hammerfell"
It makes titling the DLC stories a lot easier. If they did it with Skyrim, it would look like this:
The Elder Scrolls: Skyrim
The Elder Scrolls: Dawnguard
The Elder Scrolls: http://tarr.uspto.gov/servlet/tarr?regser=serial&entry=85634522
... (other extensions on Skyrim)
The Elder Scrolls: Hammerfell
... (extensions on Hammerfell)
Keep the same engine. Improve it over time. Keep the series alive via DLC and retail box.
When Hammerfell would come out, yes, release the retail box. it would include the Master File and resources for Hammerfell only, so it could be the starting point for a lot of people.
One game purchase necessary. All other content extensions available via DLC.
Of course, the DLC version of Hammerfell would cost the same as the retail box would. Even though distributed as a DLC, it would be a whole new game.
Anyway... just idly rambling here...

Seriously? You want the elder scrolls series to end? Have you played any previous games? The PS3 holds the PC back as well. Do you really think there won't be new consoles next ES? A fail of unimaginable proportions on your behalf...
