Hopefully the aircraft can be removed from the water before it is too badly damaged by the action of the current and tide, in it's current location it is likely to have high loads inflicted on it.
There maybe lessons to be learnt about ditching from this airframe. For example I'd be interested in the manner of the engines separation from the pylons. I'd imagine there will be a fishing trip for the engines in the next few days if they have indeed separated from the wings.
I'd also be interested in how much (if any) damage the rescue boats did to the wings and if that caused the aircraft to sink faster than perhaps it would have, possibly due to rupturing fuel tanks. Would be good to update the understanding of possible floating times in ditched aircraft and the effect of fuel tank air/fuel levels on aircraft buoyancy. Don't get me wrong I think the boat crews did a great job and almost certainly prevented more serious injuries due to exposure to the very cold water.
