Ed Stetzer is at the top of the list of great minds in church planting (among many other things he's incredibly knowledgeable and well spoken on). He recently gave a talk detailing what it takes to be a church planter & you can find that video below.
The Exchange June 2011 - Are You a Church Planter? from Ed Stetzer on Vimeo.
Guys I know who have planted churches in the last year or two:
Tony Rambo - The River Church
Dave Tilma - Ezra Church
Michael Behm - Real Life Church
Brad Kindall - Gallery Covenant Church
Ryan Lunceford - Advance Church
David Sorn - Renovation Church
Chris Wachter - Hiawatha Church
Michael Binder - Mill City Church
There's about 5 more, but I'm drawing a blank at the moment who else should be on this list.
