tf2 is a rewrite of tf. Our goal at the moment is to release it into Fuerte. It is targeted to replace tf. It is mostly a redesign for easier use in code. It's also noteably lower overhead and doesn't require anywhere near as many dependencies. The design page can be found here http://www.ros.org/wiki/tf2/Design.

It is backwards compatible with tf on the ROS interface thus tf and tf2 can work side by side.
