Sadly, I fear, any upgrades for MRA 4 will be way down the pecking list. Let's get her into service for her primary role, eh?
Also, we're aren't buying that many and so I dout she will ever go to Afghanistan.
On the 2-seat fuel issue. It's great for training, but, fuel is life in air combat and leaving a bit behind to carry another bloke, no matter how important it might be, is another matter. Don't forget, that the external fuel tanks will be ditched pre-merge and so that extra bit could make all the difference. Remember Spitfire/Hurricane vs ME109 about 70yrs ago? The ME109 was superior in nearly all areas (apart from Spitfire's slightly better sustained turn rate) and was most usually beaten because it was running short of fuel.
Just my opinion though...
