The only aspect of COD I don't see the developer continue to work on are the Campaigns and Missions for COD. The existing FMB and any updates to the FMB gives the community more than enough tools to make very good campaigns, and missions, just as they were done in the original series. New aircraft will be added to COD thru those developed for other theaters and from the SDK that will be provided by the developer to the community.
They still don't have a bonafide "career" system - medals, promotions, etc. - unless I missed something recently. Even with the FMB and everything else getting fixed, without a career system, CloD is still lacking something
