You are correct, especially considering the remaining three release dates:
1/25/2011 Brink Release
Q1 2011 Hunted Demons Forge
9/13/2011 Rage
Rage will be huge I am sure, and there will likely be a ton of resources devoted to it's release at least a couple of months in advance.
The same would be true for TESV (although markedly larger in scope and requiring more resources); I could see the two months after Rage being the blitz for TESV where they have all of their resources recouped and from 9/13-11/?? a very full throttle marketing campaign could be enacted with all of Softworks dedicated to it.
Just on that assumption puts the release in Holiday 2011 range.
I wasn't aware Brink had a concrete release date aside from Spring 2011?
Either way, I'm positive that none of Bethesda's remaining published games will get in the way of the TES V announcement. It's not even worth thinking about it. Bethesda will figure out a way to best hype up all of their games, including TES V, at the same time, and release them so they don't interfere with each other.
I'm same person as 1 oblivion, just a different username (hope it didn't offend anyone). Anyways, I have a friend who works in the video game industry and he just informed me that he does know some people at Bethesda Softworks. I asked him if he knew or could find any information about this little discussion we are having and he said he would check around today and get back to me! I won't mention companies or names so that nobody gets in trouble, but it is looking promising! Hopefully we can get some answers (LEGIT) today!
Lets stop posting these kinds of stories guys. Look, you could be good friend's with Todd Howard's wife for all we know but unless you can provide is evidence of that, telling us a story is pointless because we have no way of knowing if you are telling the truth or not. Your friend may very well know people in the industry and may very well be able to convince them to break their NDAs and tell you what they're working on, but unless you can give us solid proof there's no way we can believe you.
