The Struts team have announced a subproject of Struts called ‘Shale’, which is an MVC framework based on JSF. This project is also earmarked to become Struts 2.0 (as no Struts 2.0 release based on the existing Struts Classic 1.x code line is planned).
Time will tell how long Struts ‘Classic’ now has before it becomes phased out. Shale is an entierly new codeline, based on JSF. More details and FAQ are in the announcement from the Struts team.
