Vince is such a psycho I really wouldn't put it past him to completely change plans and lie if Meltzer reported something that was supposed to be a secret.
Like JB said, who cancels their own TV if they still want the promotion to be run? The problem with the FCW guys really isn't with their ability to wrestle, it's with their ability to connect with an audience.
If I had to speculate, I'd say that this was in the works for a while and was intended to be announced after WM when they do the post-PPV purge. But for whatever reason they had to give notice to get out of their Bright House deal, and once they did the story leaked from the network side. Because they probably don't have finalized plans for what they're doing with developmental post-WM, they had to go into damage control mode.
Again, I can't imagine there won't be a developmental territory, and I can't imagine said territory won't have TV. And I wouldn't be surprised if they stayed in Florida because there are economic advantages to saying there.
