USA Network has talked of wanting Raw to increase to three hours in the fall. The belief is that is guarantees the network one extra hour of very high ratings every week, thus enabling them to maintain their status of being the most watched network on cable television. The thought process being the move is that if Raw starts at 8 p.m. more often, people will get used to tuning into Raw at that time, and it will lead to higher ratings in the second hour in particular.
They also made the suggestion of Steve Austin and Undertaker being regulars on the show, even if they can't wrestle. On the WWE front, they aren't too keen on making Raw a three hour show, every single week. They think this is the last thing they need. Although, if they go through with the move, they'll likely get a rate increase from USA.
I'm up in the air on this one. I think there is way too many hours of wrestling per week right now. It's tough to figure out though. I felt the Nitro move to 3 hour screwed that show. It was doing killer ratings, but then too much time just killed it.
I would vote no for now, unless either the brand extension was dropped and more talent was on Raw to pull this off. I for one would probably like to see Smackdown go away. If this were to happen, then I would be very happy with a 3 hour raw.
