I have no idea of the finances that HTC has to work with, but I sure hope that they add more staff if they plan on expanding the WWI arena, hope to continue adding new aircraft, hope to add more gv's, and hope to continue improving the over-all game play and sim experience. Obviously, if finances are an issue there are talented enough people to volunteer their time to work with modeling aircraft and gv's (not flight models, just the "shells") to take off some of the load, but I've suggested that before and been called "arrogant and foolish" in thinking anyone else in this world could do that besides HTC.
There are already plenty of aircraft to pick from to keep most people satisfied, but historically speaking there are some major holes in the lineup (He111, Beaufighter, Pe-2, Oscar, etc). The GV section could use a boost in selection, too (but no more late war super machines like the Firefly).
Oh... and lets not even start on fixing many of the current issues with many of the current aircraft, issues that have been backed up with hard data and evidence but yet get passed over. How about tracked vehicles being able to "zero turn"? How about matching aircraft performance/abilities with historically accurate data (again, with data that has been presented)?
