Motion provides motion-graphics creation with real-time previews, procedural behavior animation and Final Cut Pro HD integration. Available as a stand-alone product, or now available in a Production Suite, and a price point of only $299, Motion provides studio-quality video motion graphics at a mere fraction of the previous cost.

[Update] Available in Software Update for users of Apple's Final Cut Pro HD & DVD Studio Pro is 'Pro Application Support' which presumably provides support for Motion to be used with the other apps, bringing their version numbers to 2.1.
