As far as I can tell, there isn't a BF:H catch-all yet, just some battlefield 3 posts that it has derailed and a Beta sign-up thread.
I'll start with the bad news.
We have also been working hard on the parts of the beta that aren't the game. Sound weird? Let me try and explain: You know the old saying about icebergs being 10% above water, and 90% below? Heroes is a little like that. There's the 10% game part you can see, and the hiding 90% is what we call the 'backend'. The backend does a lot of things. From running the website's features and looking after the items you have, to collecting the results from each Heroes game and matchmaking players into games.
We have received lots of great feedback from our beta testers. So much so that we are now ready to enter our next phase. On Friday evening (6pm CET) we will be closing down the current Closed Beta and moving our focus to polishing the backend. So for a while there will be no closed beta available to play. We expect to re-open the beta early next year.
Speculation says a summer '09 release.
