Here's what we know: Nothing
Other than the fact that we're getting a Walking Dead themed house, and that there were six permits submitted (which we don't even know if some houses are or aren't dual path yet), we personally know nothing. If you're willing to risk your reputation on here and say that something is a 100% going to happen, then do so and we'll see if it comes to fruition.
I suggest that instead of continuing to base arguments on rumors and other speculation that you might've heard here, or from a friend, or the guy that valets the cars at Universal, that we at least wait till we get the basic gist of what this event is gonna bring this year from the website itself. I know that this is a speculation thread (and by all means keep speculating), but it gets a little repetitive and redundant when you basically see the same post/argument, talking about the same thing for the past 20 pages. I personally have faith in Universal, not because I've grown to love the event, but because they're a business. They know that they have to knock it out of the park every year if they don't want to see dwindling numbers and sales. Harry Potter might be a cash cow, but Horror Nights is a cash cow and alot easier to profit from. Especially from liquor.
Something else I wanted to mention. I, like everyone is really sad over the fact that Ray was't asked back to join the team for website design this year. This doesn't mean they might dumb down the website though (like Hollywood's. Sorry West coasters). They might just want to go in a different direction than years past.
Just in the last day I've seen people demean others here over certain opinions they've made. Like Mark (mz_) has mentioned, we don't want to hide posts or lock topics. We just want people to be civil to each other. When it comes down to it, we all have one thing in common. We all love Horror Nights and are all very passionate about it.
tl;dr : Chill out peeps and be patient. Speculate about the event, not argue with each other's opinions.
