Either way you wouldn't have seen Bret.
There's no way they're pulling Bret Hart in and giving him enough money to shrug shit off just for a fucking DVD. The only reason he has "more power" over the shit is because Vince wants him to. Look at the Warrior DVD. It's not like you need the actual guy to make a great dvd so long as you have footage.
I guess we can debate about it all day but IMO if the Hogan/TNA thing didn't happen then Bret wouldn't have been around for at least another 2-3 years. At least not in WWE. I would even bet that Hart was in talks with TNA and when they spent all their time and money on Hogan, Bret Hart was like "fuuuuuuuuuuuuuuuuuck you then"....
