PHB II Classes -- Epic Progression?

[Azaar]

From looking over the Wizards website, I see nothing in regard to epic-level progressions for any of the PHB II classes (beguiler, dragon shaman, duskblade, and knight). The beguiler in particular interests me the most (though I'm still a ways distant from epic level beguiler), but the others also intrigue me. Is there any sort of epic progression, or do we simply use our best judgment on what sort of epic progression the class would have (like breath weapon and draconic aura for dragon shamans, for example)?
