Metropolitan governments

As municipal boundaries become less and less relevant in our metropolitan areas which are becoming almost as "urban" beyond the main city's city limits as they are within them

-and-

the need for integrating major metro areas in areas like transporation, police, and other civic services...

do you believe in the 21st century we will see more and more of a trend to metropolitan government, something akin to Miami/Dade or metro Indianapolis?

Will metropolitan government, a strong and adequately empowered level of government, become more and more important, perhaps the way that counties functioned in the past, but with a lot more power? Will our cities become less relevant in their governmental roles due to their inability to effectively offer services that should be metropolitan in nature?>
