I don't think Bret was bitter in his book.....he just told the truth. He was naive in thinking that Vince wasn't going to screw him. I think now he's come to the realization that it was just business. Part of the deal of him coming back is a Hart family DVD box set. I think this is the driving force of his return. Not only does Vince have all of the WWF/WWE footage of Bret, Owen, Davey Boy, The Anvil, & The Dynamite Kid, but he has over 20 Years of Calgary Stampede Wrestling footage & that is something that Bret has always wanted. I don't think he'll have much to do with the Hart Dynasty.
