I understand Your point of view but...even if I enjoy the other sim, it seems me...a bit "gamey"....
Having a DCS level WWI will be great, the same if they develop WWII, this is sure.
But, if You consider the simplicity of a WWI the time to develop a single aircraft could be very short compared to others, the bug list could be short as well (no system to model no bug that could pop up) and with a small team involved it could be bringed on at a good pace.
Then, if as it seems there will be a good interest, the volume of sell could become a good revenue for ED.
We could have a complete WWI scenario in a short time (compared to others timeframe) with historic planeset and a couple of map (size smaller and so easier to develop) and a good cashflow for ED others development.
