Looks like Bleeding Cool jumped the gun on this rumor b/c over a week ago they stated that Schumacher hadn't heard anything about writing Batman comics based on his original plans for the bat films.

Dustin Nguyen also denied knowing anything about it as well.
It takes him nearly 20 yrs for him to figure out what his original intentions were for the Batman films he directed. Well whatever it maybe has gotten me interested
Damn it. That really sucks.
