Again I'll say -
Hasn't Clive Owen aleady been selected for the role? It was my understanding that Brosnan would do one more film and then Owen would take over. Now with this most recent change it becomes obvious that Owen will just step in one movie earlier than planned... 
Unless, of course, I was smoking crack again 
Personally, I think Owen is perfect for the role. Possibly the best casting choice since Connery. Take a look at his BMW short films. They couldn't cast someone better than him.
Also, I prefer 
From Russia With Love over all of the other Bond films. Comes the closest to the books IMNSHO. 
So far, Connery has been the best Bond. Lazenby's film would have been the best Bond film EVAR if Lazenby hadn't been in it. Moore was too campy (with the exception of 
Live and Let Die). Dalton was excellent in 
Living Daylights which hewed closer to the books once again, but his second film as Bond suxxors. Brosnan was good and provides a nice balance between Connery and Moore, but he was hampered by the big Hollywood crapitization of the franchise. 
At one point, Tarantino was vying to do a version of 
Thunderball since the rights were still up for grabs, but then the Broccoli's nabbed the rights after all. I would have loved to have seen Quentin's take on Bond. Oh well... He has said recently that he'd like to tackle a remake of 
Casino Royale. Hmmm.
