What stuck on hearing Jason about the new FC was that they primary intend to bring in the planes from ROF much as they are now by refurbishing the lot, meaning adapted to the upgraded/new engine.
Same for the maps, which is a easier job while but maybe buildings and so would get extra treatment in way of better/updated looks.
That job will be handed out to a third party that already worked for them & will be paid for it.
The first module may take something like 10 to 12 months.
To keep their WW1 way of behaving/flying/FM those planes need a different approach compared to the WW2 ones so merging both in the same missions may or may not be possible.
However MP would happen on the same master server, but where new multi threaded net code would need way to much work for their 2 head programmers already completely tied up for a rather extended period.
So no way to free them for an extra long job that would only benefice an MP crowd that makes out 5 to 10 % of the paying customers.
The first intend is to import as fast as possible the existing ROF contend in order to add new planes later.
The first plane set consist logically of the most popular and modern plane models.
