I don't think there was ever much chance of Nolan directing a justice league movie. I don't think it'd the kind of project he'd do. And I'd rather it that way, not because I don't like him but because I'd rather him now concentrate on original projects.
As for a batman/bruce wayne cameo, I think if Bale turned up I'd have a heart attack with how cool it would be and I'd go mental with excitement, but at the same time I think it's ultimately better if they leave the dark knight trilogy as its own stand alone series and then have someone else to reboot the series. Which is a difficult thing to day as I'm a huge fan of Bale in general and love his batman performance.
The long and the short of it
