Regarding Snitsky, the current plan is for him to stay with ECW and become their top heel. They’re only airing vignettes of him on all three programs so that he seems more special, not because he’s possibly moving to another brand. He’s going to be feuding with Bobby Lashley soon.
Regarding Sabu, he did receive his release, but he cannot appear for TNA or do media interviews for 90 days. He never gives interviews, so that’s moot point anyways. He can work indy shows if he wants.
