I mentioned something similar to this in another thread. I don't like the same set up on all three shows. It defeats kayfabe, and seems lazy too me.
I think all three shows should be ran in a matter that makes them all seem separate from each other.
WWE as RAW mon Monday nights. with the HD set.
ECW as ECW. With a more gritty public access/independent/low budget look.
SMACKDOWN becomes WCW (Dare I say Thunder?) and gets the old WCW Nitro logo set (My fav wrestling stage ever.) And a WCW/TNA style lighting/camera set up.
Also WCW should have the rubber covered steel ropes. And ECW should have there logo on the mat.
RAW and PPV's are the only ones done in HD.
Thats just my opinion. I think it would help crate a "Kayfabe" sepration in brands. And roster jumps would mean more because the production value changes between shows, so the talent will look a little different and or there entrances will be bigger or smaller.
