The way i see it:
1. What we saw in the expo about whats coming to elite is about 40% or more allready developed.
2. At March of 2018 when Q1 goes live or even much earlier, main development stops for ED until 2019 and the game gets into maintenance mode. All stuff announced will be finished by then easily and only releases will happen till the end of the year. Thats 5 full months from now, plenty of time for getting done some ships.
3. Most developers of the team will work in the other company projects for the rest of the year.
Benefits:
1. Playerbase gets to cool down after the so badly implemented grind-orizons, and FD gets to be the good guys that finally listened. The grind served its goal for 2 years and thats success in the company's book.
2. The "good guys" release FREE content for horizons users but forgot to mention that this will "force" non horizon users to.. spend money to buy horizons because each step to that direction makes the game more and more unplayable if you dont own horizons. Thats income so no freebies here.
3. Extra man power that drop ED development for a year will seriously boost other projects so thats serious income and publicity.
All in all, ED is in a very stable path but clearly rests in its glory and always drops only the absolute neccesary bones to keep the dog "happy".
No complaints though, i would do the same thing probably.
