I can understand not wanting to move back into the silliness that was prevalent in the Roger Moore era, but I think the series is starting to lose its identity a bit. There are certain staples of the Bond series that give it its charm. Bond will walk in, flirt with Moneypenny, get chewed out by M (granted, that's still there) and then hop on down to Q branch for some gadgets and chastising about proper handling of said gadgets.
Those are part of the Bond mythos, and I think it's a big mistake to remove these elements from the series. Without them, there's little to diffrentiate the Bond series from other spy movies. Don't get me wrong, I loved Casino Royale. I just hope that the series doesn't forget where it came from.
Pretty much what JacksonArcher said, we've had twenty years of that stuff and I think we've earned a bit of a break. Over the years people started to believe it was merely the fact that Bond said certain things and did certain things that made him Bond, rather than how he did them and said them. They pretty much became vestigial and had no meaning.
