I would want a film noir reboot set in 1940s about a previous Wayne; with flashbacks or just an opening featuring an even earlier Wayne as Batman in the winter of 1888 hunting Jack the Ripper in London.
I want a different kind of Batman after Nolan is finished-- a legacy origin rather than arm chair psychology trying to figure out why someone would dress up as a demon in the night.
To take Batman back to the 40s takes the emphasis off of technology and puts it on a detective story and simpler villains (before the age of terrorists, skin heads, assault rifles, cell phones, etc).
