Long story short, because Warner's felt Batman Returns was too dark (IE, not marketable enough/not enough a toy commercial), they threw out Tim Burton, brought in Joel Schumacher, and the rest is history (that history being that the series sank until we "Batman and Robin" killed it).
There's been a lot of rumor about how it would have gone, but a common thread I've seen is Robin Williams as the Riddler in the third film, and Billy Dee Williams as Two Face in the fourth.
Since my childhood Batman was basically Burton's, I don't really feel like a continued Burton direction is all too alien. So what if Burton continued as the head of the Batman film series?
