The Fiat group esentially has the Fiat, Alfa-Romeo, Maserati and Ferrari brands being commercialised at present. They also own the Lancia brand (as far as I know).
I have wondered whether or not they will revive the Lancia name. It would be awesome to have a modern version of the Integrale or Monte Carlo. Also, whereas the 159 just loses out to the 3 Series or C Class, a Lancia branded car would have more prestige than these.
I really hope they do revive it at some stage.
