I would say its a free for all kind of deal. It has worked supriseingly well with Duke. I guess the reason for that being a core set of people doing a large part of it and everyone else fitting there work to the "norm" so to speak. I suspect the same thing to happen here.
There will be a HRP for sw just like the duke version as soon as there is enough content but the true enthusiasts that can't wait for it will most likely have to update there sw texture by texture and model by model.
