I have to agree. Its obvious in several ways that this isn't the same landscape as 1999. WWE has to push into more media (aka more ways to get content with handheld devices et al. Youtube is a start).
The WWE specifically has gotten much better over the past year. The return of old faces shows me that they're trying to push their way back into the mainstream and will succeed. They have gotten a hell of a lot of press over Wrestlemania and if they book SummerSlam the same way, they can get a lot of press here in Southern California.
As far as cornerstones... I think CM Punk could bring in some viewers that wouldn't have watched otherwise but he doesn't have that cross-over that Cena and Lesnar have. Brock will help ratings/buys for the short term but I don't expect him to carry any load. Rock, he's filming another flick and will be back in a few weeks (months, ppvs, however you want to gauge that)... Cena, he's still the top guy, regardless. There's a lot of young talent that can bring more viewers in but have to continue that cross-over like The Miz has done recently.
There is no shortage on talent. Hopefully they will be allowed some liberties with their characters and make the WWE larger than life and capture an essence of days gone by (I don't mean recreate the Attitude Era... hell no...)
