This is getting a little chat-boxy, guys.
Anyway, to try to add something (relatively) new, I am quite comfortable in saying that TES V will be announced soon (GI or not) due to their new Skyrim trademark on top of their old one. They did the same type of thing right before they announced Oblivion, and I think, Fallout 3 too.
There is currently a legal battle over that, so I doubt it will be the GI cover.
