I don't think he's ever going to sell ECW or WCW, for two reasons: 1). Because it makes the WWE 24/7 service more attractive. 2). Because the ECW DVDs that have been released were huge sellers.
I do think that Vince McMahon should focus more on Raw and SmackDown!, and limit his involvement with ECW to finances. Vinnie Mac has a great mind for sports entertainment, but he doesn't know jack shit about hardcore wrestling. He should let Paul Heyman operate the brand and give wrestlers the same freedom that the ones in TNA have, both on the mic and in the ring. If he doesn't, WWECW wil quickly become boring and even those of us that have been willing to give it a chance will eventually just give up.
