I lurk but I really have to chime in on all this "It won't be good because P&T aren't scary" stuff.A while back it was said P&T were working on a design for something at Universal which is assumably for HHN.
Fangoria sponsored two houses for HHN in previous years,so why can't it just be Penn & Teller present _____ just as the Fangoria houses were done.Personally I believe it will be that way,a house designed by the two but they will not be in the house in any way,just a possible rumored 3D concept of dark magic put into a house coming from P&T minds.
If this house is infact 3D and done correctly,this house could be a HUGE success.
