The long: What's the point, really? Assuming that 50% of the rumors are accurate, there is still not enough information to make any kind of informed decisions. They is so much BS and chaff, that you can't separate the fact from fiction until after the official rules are out. Then even after they are out, it still takes months for every to get a grip on the changes to the game.
Take a look at this. This is The Back 40k and my new favorite community. They usually have their heads screwed on straight. In that link they are giving a review of some rumors for the GK Codex as reported by Blood of Kittens. You can read down them and see that even 4 months out from release the rumors are fairly accurate at least in kind of a general way, but not accurate enough to relate the subtly in some of the rules. None of that was readily apparent until you could get the codex in your hands.
And even then, the real impact of the changes do not come through until months later. That point was illustrated very well on World's End Radio in a recent episode. (I would link to it but that would mean re-listening to a 3 hour podcast.) They were talking about their review of the Dark Eldar Codex and how they were way off on how some things worked until after they had played many games.
The kids over at BoLS, blood of Kittens and everywhere else that reports rumors does a disservice to the community. I know why they do it. It is the same reason that they do the worthless "Caption Contests" and idiotic Goatboy articles. They generate hits and those hits are how they sell advertising. It is just like the local news. They do not care what they report as long as you read it and they can get real paid.
I can wait. I am gonna wait. Don't get me wrong, I have my pennies saved and I'm going to get the rule book the day it is available. Then I am going to read it. Then I am going to write about it. Them I am going to read what other people write. Then I am going to play lots of games and only after all of that will I have enough information to make any sort of informed decision.
