Just quoted parts of your post.
The remake/rehash all starts from the concept of "Anniversary/Reunion". That's ALL we have right now, that's ALL we know. The one thing about speculation (and we go through this every year) is that it WILL contain things people WISH for, based on what we KNOW!
We all might WANT ORIGINAL, but going by the 20th Anniversary, and even the tag line of "Twenty Years of Fear" ideas of REUSING old concepts from Houses, Scare Zones, and even Icons will be in people's minds.
We need to respect the speculation of others regardless if YOU like the idea or not, regardless if it's ORIGINAL or NOT. As stated previously, we all get a little anxious around this time as we wait for that little bit of OFFICIAL information to come out, hopefully through a site update.
Regarding Roddy. I think we can end the debate on if his ideas will be involved at HHN XX (knowing his resume says he had a part in HHN XX), why? We'll never know for sure unless MJR or another member of A&D says "Yes, some of Roddy's ideas are/were a part of the event".
Let's get back to speculating on what we THINK WILL happen at the event this year based on what we KNOW.
