You should already know that none of us have a developer's insight.
And not even the developers will ever be sure if something will come to pass.
So will it happen? most likely, since they've done ENT/TOS/DS9 bundles.
Unless of course there is some kind of copyright envelope surrounding TNG/STV.
Voyager ship pack is near top of "ship pack" list
Voyager and TNG bundles are both planned but no ETA
Voyager bundle hopefully in 2013 with new interior and either costume pack and/or item set
Likely when get closer to adding Delta Quadrant
Delta Quadrant likely to happen before Gamma Quadrant
