The Endless Universe package is a standalone version of the two expansions; the base game is not required (this is because at the point Kalypso decided to do this, Paradox owned the rights to the base game).
But Kalypso recently obtained the rights to publish the base game from Paradox (Koch being a subcontractor or subsidiary of Paradox), so they're now going to be releasing "full" bundles as well with updated DL translation, but really all you gain there is the original campaign and the option to play without all the enhancements that have been made in the expansions, neither of which is a big deal to most people; the expansions supercede the base game, so for most people once they have them, they won't touch the base game any more afterwards.
So if you have the original Paradox German release or not, makes no difference; the Expanded Universe bundle will bring you up to the latest and greatest with the new translation.
