Sure, but it isn't really all that much:
It's said that was done to make up for the shitty ECW PPV, as a special gift to the fans.
There isn't really a story behind it. Finlay is just one of the oldschool hard hitting type of guys, like Taker, JBL, and so on and that's just the kind of shit they pull, ribs and all of that. It wasn't planned or anything, it was just him slapping the piss out of him. Someone at PWInsider said that part of the reason it was done was because Josh showed up and didn't shake Finlay's hand. Yes, Finlay is that "important" backstage.
The word going around right now is that the serious DX, the "more hardcore" DX, is being done just because of the VKM stuff in TNA. They don't want people to watch RAW and see DX acting exactly like VKM is making it seem like.
Nothing much new here. He'll be out for a number of weeks, and after that who knows. They mentioned that it could be a good idea for him to turn face when he returns. (Personally I could see him coming back as an even stronger heel. He was a "pretty boy", but when he returns he'll have scars and will be "disfigured". )
This is all about Tazz. His contract does end soon, and some people are saying that he's asking for quite a bit of a raise and other demands. They say to take that with a grain of salt since other people are saying that nothing's been mentioned about Tazz and his contract at all, but it is indeed possible that he'll be leaving the company when his contract ends.
