Maybe I'm just seeing it in a distorted way, but at least the final volumes are being released in one form or another.
Tokyopop aren't releasing the final volumes in physical form of some series at all.
The whole strategy has to do with consolidating any unprofitable areas. Piq never gained the success it should have, so closing it seems logical. Maybe ADV will do something similar to what Manga said they'd do (the whole trade in the volumes you've got for the entire set), time will tell.
And CG, Renewal hasn't been announced as licensed at all yet has it? There's still a chance that ADV have it, or are in the process of bidding for it.
