What I'm really hoping for is that they don't try too desperately to pull out the "we have something for everyone" card. By that I mean, I don't want to see one match be a squash with Khali, the next segment be a comedic Hornswoggle thing, then have the women in a bikini match, then have Undertaker doing that ridiculous "I can conjure up lightning" stuff, then following it up with R-Truth doing a rap segment, then....
Hopefully they just decide that they should put on the best possible show, with lots of action, some VERY SHORT video packages (3-4 minute packages turn people off and leaves nothing left for enticement or anticipation, but a quick 45 second thing could get people to say "Hey...what was that? Maybe I should check out Raw the next time it comes on and see what they were talking about") and most importantly, that they don't just get discouraged on the first night having flopped, because it definitely will. People won't be used to the channel switch, they'll forget, they'll think its not being shown that night, etc, no matter how many times you remind them. They have to remember that most people have no clue what MyNetworkTV is, because not only is it part of the standard lineup of "basic channels", but it doesn't have any high-profile original programming, it has an INCREDIBLY generic name and logo, and so forth. There's no doubt about it, Smackdown is going to struggle with ratings for a while being on such a network. But maybe that will just make the WWE try harder (and hopefully not ignore ECW and Raw in the process).
