It was not planned for the initial release, but we are working on it for an update release. Note, this is the same approach we took with Java EE 5. First release is Java EE compatible but single instance. Update release adds HA and centralized admin. mod_jk provides service availability for GlassFish v3.

Yep, that's the plan.
