You did, but that was a while back.
I'm not sure of Idris Elba becoming Bond. From what I seen of him in that detective type show he did (forgotten it's name), he's a fantastic actor, but I don't think he's 'Bond' enough for the part. Craig made the character a little more rugged than was the norm, but he still kept the Bondish elements. I don't imagine him being a ladies man, for example.
And what Moose said too. The films all tie together now, unlike before, so it'd be actually impossible to explain the skin colour change. I know everyone accepts when an actor switches in the role, as that can't be helped, but I think that might be a step a tad far. I'd have him as one of the other Double 0 agents, in a secondary role, one where he keeps appearing. I think that would be a cool direction to go, as it's never been really done before.
