The Targ doesn't do anything but follow you around. Not sure how that qualifies as "gameplay affecting"?
True, the Targ does nothing useful for gameplay, however, it was originally one bonus; Targ for Klingons and Tribble for Federation. The fact the Klingon bonus does nothing doesn't detract that the Federation one does. (Damage Resist, Bonus Damage, Regeneration buffs).
Just to stop quibbling though, I will remove it from the original post.
Fair is fair. Everyone should... benefit equally in this move. Put it all up. All the pre-order items, Liberated borg, Taco Shuttle... all of it.
The Class 8 (Del Taco) Shuttle is also a preorder for Orders from Gamestation UK.
Liberated Borg, as it will sell very good i guess, at least as good as caitian, if not better (also it's a deal that should have never been removed from lifetime-sub).
I don't think that Referral Items will ever hit the c-store, since they, like tribble of borg or the tamarian badges/titles are reserved for special ocassions and have to be earned (not bought! and yes, i know that there are some people who "buys" their referrals instead of "earning" them. They exploit the system.).
