I doubt that AW would be the experience they would rely on since they have their own demographics from Dawn of Aces which Dale et al created to draw from. Korea is another kettle of fish and suspect would be quite abit harder to put together.
AW wouldn't be the sole experience to rely on but to dismiss the lessons learned from it and other WW1 online sims would be foolish. While there is a lot of vocal support for a WW1 online sim within the online flight sim community, that vocal interest does not necessarily mean that customers will pay for a WW1 online sim.
Brooke and others have brought up the example of the WW1 arena in AW. It was a fun arena to fly in but in most cases you'd only find 5-6 people in there but usually it was empty. Flying Circus was released around '96-'97 and was probably the best WW1 online sim to hit the market. Unfortunately, again, vocal support didn't translate into $$$ and the failure of Flying Circus helped lead to the demise of SimGuild.
You bring up DoA, same problems as AW and Flying Circus. Lot of vocal support, far more vocal supporters than players.
The fact is, the consumer has shown the gaming industry that while there is a lot of vocal support for a WW1 online sim, there is far less support for actually paying to play one.
