There is precedent for this. Again, Arrested Development went off the air before it was resurrected by Netflix. And who can forget Sherlock from BBC? The long hiatus between series 2 and 3 did not dampen the exciting and ratings for the show. It just goes to show that if you have good material, fans will keep coming back.
On top of that, have a series go off the air and letting fans have the chance to revisit it is a good thing. Furthermore, consider how Arrested Development grew its fan base after Netflix subscribers who previously did not watch the show get a chance to see it online.
