It's a tricky one - while most of us here don't want to watch an hour of Nash, Hall et all, they still have audience recongition value and that's priceless when you're coming right out of the gates.
They have to strike a balance between catering to that (mythical?) casual wrestling audience and their current audience, those who'd be quite happy to watch a two hour show made up of two 45 minute X-Div matches.
What I wouldn't do, under any circumstances, is open the show with JJ delivering an in-ring promo about how he's just won his belt back - right off the bat that'd just give a poor man's WWE impression and that's the last thing they need to do.
So, start with a crazy arse X-Div match, let the ususal suspects go at it for 20 minutes and wrap it all up with a clean ending. Follow that up with some kind of skit or promo or something with the likes of Nash, Konnan or someone similar.
