Never,
The Ent-E vanished in a mystery, why would they ruin the fun and tell us what happened.
IDEA!!
Make searching for the Ent-E an endgame mission to go along with planned Admiral and Fleet Admiral level updates (read Massively visits Cryptic) However, it could end up as a featured Series even XD.
BOO!!! Who needs these useless non-combat pets?! I want a flyable version!
+1 to that.
lols. Yes, we all want a flyable totally unarmed ship that can go warp 1 in sector space for a few seconds at a time, then stop and have to have a cooldown like the transwarp does.
