So opening new bases choice become more important as the the limited of 600 fleet is possibelle to protects our HQ from others who want to compete with someone else,so we have to think more about choice of bases.
So pro 700 to 800 means more growed in later years and make more easier to compete with other airliners and pressure them,which usually the exensions leads too.
Growing 100 to 200 more is probablly only be used by a smaller group of players.(including me)
other hand: 600 max outside HQ is protecting the largest group of players with ave. skills or time and also have a chance in later development.
At present time commuter development is mostly ignored by the large players as they can easy take a 20%LF on some shorter flights to utilize a plane to the max.
So with the 600 limitation the HQ development can gett more attention and also leads to more flights as there are plentyfull slot compared to previous games and this sector can gett more competition aswell and don't forget cargo demand will rise too.
Also the demand will grow if a base is very busy,so there will be option for expension.
So there still some gamming possible,as usually the bigger players are based t the largest bases available.
Extra challenge can be to try to gett the largest outside base(maybe idea for a new achievement

)
Would be great if can be cleared up by Sami if this can happen or not,as this is important for game developent.
