The story sensationalizes a bit doesn't it?  They are making out the discovery of a camp occupied for roughly four years in the early Imperial Period as being a breakthrough in research on the Romans in Germany.  It is undoubtedly going to be a financial windfall for the town but will hardly represent earth shattering or even groundbreaking discoveries unless they find something really extraordinary.  I read a book recently that says there are something like 600+ known Roman fort locations in Europe, most of which we only know the location of and very few details.  The best sites are all in Britain and it is difficult to say anything with certainty based on archaeological and inscription evidence.  Unless they find written records, just about anything hey say about the history of the cap will be pure speculation.  Based on the nearby towns location, the fort is not even on the Limes that I can see.  Looks like the Telegraph has sexed this story up to make it better reading and cherry-picked quotes that sound better in the bargain.Outside the discovery of the location of Troy, I can't think of the discovery of a single site in the past 100+ years that was actually earth-shaking or that significantly altered our view of history.
