What apps work with Versions?

[JohnDoe98]

Apple has advertised versions as a feature in Lion. Presumably upon purchasing Lion at least some apps will have it working already. Anyone know what those apps are? Same goes for autosave.

Any chance on an updated iWork release alongside Lion?

Preview and Text Edit support Versions. I expect iWork '09 to be updated to support this or we may even see iWork '11.
