Why doesn't the company that makes the SuperBug for FSX step in and offer that for DCS? They're sure to make a killing, so to speak!
While DCS has been heading in the direction of FSX, VRS has been trying to make FSX into DCS. I don't know if it would make sense to compete with themselves by supporting DCS when they are trying to market their TAC Pack and license it to other FSX developers. But, if the developers that were supposed to use TAC Pack are making DCS products instead, then VRS might have little choice but to join the DCS 3rd party crowd.
Personally, I would like to see both products succeed to maximized choice and competition for combat flight simmers. But FSX is technically a dead engine, whereas DCS is just ramping up. It's a gamble to move on to something new, but its a sure loss to stay with the obsolete. If you are in the horse and cart business when autos first appeared, you can safely keep making carts for many years... but one day, everyone wants cars/trucks and almost no one wants carts/wagons. Everything hinges on how well DCS and its 3rd party addons satisfies the community. They will have phenomenal success if they end up uniting many different groups: survey simmers (think SF2 crowd like myself), study simmers (Falcon 4/Jane's F/A-18/A2A FSX crowd), recreational simmers (FSX crowd as they are not necessarily study simmers), single player simmers, multiplayer simmers, etc.
All I can do is wait and see. But based on LOMAC/FC/DCS releases, I have fairly high expectations, which could set me up for a hard fall.
