No, there isn't. It's a straw, and anyone grasping for it will yet again be disappointed.
Gotta agree with you, Freddo, but remember, all we do in this thread is grasp at straws. Personally I'm not getting my hopes up for the next issue, and now that we know that the trademarks expiring doesn't limit them as long as they file new applications, I see no reason to get my hopes up for an announcement any time soon.
The way I see it is that after the current trademarks expire and Bethesda files for new marks, there's absolutely no date that they have to announce TES V by for another 3 years, when the newest marks expire, though by that time, god willing, it will have been announced and released already. They could announce it this month, they could announce it a year from now, but at the moment we have no idea which it will be.
On the bright side, as others have mention before, if TES V has been in development since Oblivion was released, making it the longest developed BGS game yet, it should be pretty damn awesome when it is finally announced.
