Because I would have to spend some big $ to upgrade my PC to be able to fly version 2.5 and hope it flies without problems, I have opted to stay with version 1.5.8 until all the bugs are worked out. Will DCS continue to maintain 1.5.8? For example: will the upgrade to the Spitfire IX (I think promised at end of June) be available to those that still fly 1.5.8?
