Not necessarily, it's more likely to be like the romulus lairs i.e. a side mission sort of thing that isn't connected to the main story. That kind of thing was to be expected though since we've had it in every main game since ac2 if you count the masyaf keys in revelations and Captain Kidd missions in ac3. It'll be nice to see it being more like the first two where you get an armour though.
