Now, the key point here is that they are not called:
DCS: Russian Federation Army Aviation
DCS: US Air Force
DCS: US Army Air Force
There's a difference between simulating a given aircraft, and simulating a given war.
Or from wikipedia: "Modern jet combat aircraft and helicopters have a variety of complex electronic and weapon systems that are specific to a particular aircraft. This has led to a genre called the "study sim", which focuses on modelling an aircraft's systems as accurately as possible, often requiring thick manuals that rival the real manuals in detail."
Now, if you define it as "an accurate simulation of a given aircraft and it's full and complete operational history", then sure. :P But even your previously stated definition fits well with both the DCS Mustang and the A2A Mustang, since they are still being operated.
Also, from the DCS:P-51D FAQ:
Q: How is a P-51 supposed to fight in a modern Georgian war against modern aircraft and air defense systems?
A: It simply does not need to. It is up to the mission designer to put what units he or she wishes into the mission.
I think you're being a little pedantic in your replies here....Nimits originally stated that in his opinion
in wasn't a study sim because of the lack of appropriate environment. I also agree that it's fundamentally lacking especially when DCS are the devs that are really pushing the boundaries with realism and atmosphere, yet the release of the P-51 without anything related to go with it just completely goes against the grain.
You gave the example in the quote above about the P-51 simply not having to fight in a modern era against modern defense systems etc but then on the flip side of the coin, you have ED pushing their 'Combined Arms' with statements like this:
Play DCS: Combined Arms as a real time strategy game, a first person armor warfare simulation, or direct the ground battle from the cockpit of a DCS aircraft like the A-10C Warthog, Ka-50 Black Shark, or P-51D Mustang
So its all a little confusing - the P-51 doesn't have to go into battle against modern era hardware....but feel free to do all of the above...it's like reading a small print disclaimer. Personally, I'd say that paragraph alone is enough to completely negate the term 'Study Sim' when the devs are pushing it as a feature of the game/sim. ED seem reluctant to give us any indication of the way future releases will work, when they'll be and what they'll be releasing. Like many others have mentioned previously, ideally there would be other aircraft from the same era to do battle with at the very least or a range of realistic targets to go up against. To my knowledge ED have only really said that other 'classics' will be released but the term 'classics' is obviously very broad and doesn't guarantee anything to anyone.
Personally, my biggest reservation since the announcement of BS2 is that ED still don't know where they are going and are making it up as they go along. There is no coherent path of integration, they are lacking in communication and are reluctant to announce what they are committing to for whatever reason....probably in case it doesn't work out. There is no doubt the P-51 is lovely to fly but in its existing guise I won't be spending any more money on ED's products until I can see where it is all going. I'm certainly not going to spend the money on the P-51 and Combined Ops if down the line it means we have to upgrade yet again to BS3, A10C 2 and FC3 just to get their products integrated of which most of us have already bought twice over just to get to the stage of where we are now and we're still awaiting the Nevada terrain/environmental engine which could also force additional changes and cost on us.
