www.highdefdigest.com is really one of the best places for this type of information. You get all the reviews, but for rumors as well as actual news, which is all identified correctly, they are really up to date and pretty quick with the updates.
The Star Wars/LOTR rumors are entirely rumors, and if you want to discuss it, their forums may be best, but it really boils down to whether or not BD has enough market penetration yet, or anytime in the forseeable future, to sell serious quantities of movies.
I think that the answer is 'No' at this time, and so the studios are simply not planning the release yet.
At least a year, likely two years would be my guess.
Until then, at least we are getting all the big new releases on HD for us to view and enjoy. We'll still have to wait a bit for the real classics.
