The Official EoFF Before Crisis thread (link) should tell you everything you need to know about that.

Dirge of Cerebus Lost Episode has not been given a scheduled release date yet.

And hey, it doesn't matter if you made the thread in the wrong forum. Everybody makes mistakes when they're new. For future reference, questions about Before Crisis belong in the FFVII forum, and threads about Dirge of Cerebus belong in the Dirge of Cerebus forum.
