Ah, no. PMDE's story is over now, it won't be continued any more than it has been. Aspects of the plot that PK had planned may well be recycled into her floraverse story, but it is not going to be PMDE any more. It's not getting any continuation.
A couple characters like Callahan were actually making a cameo of sorts in the PMDE verse, as their original incarnations are actually the floraverse versions. Callahan's original design can be seen here (along with Pyxis').
PK is making an original story now, she's not going to continue working on what is essentially a pokémon fanfiction. If you follow her tumblrblogs, you'll get to see more about what it is. You can also read the prologue here, though the site itself is still under construction. But PMDE is no more, and the characters that cameo'd in it have their own stories unrelated to PMDE.
