Just to answer some of the common questions
* All CMANO scenarios can be loaded in to CMO, so you will to play all your existing scenarios. The aim is to have CMO recognise your installed DLC for CMANO so all the content you already bought will just appear in CMO, assuming we can iron out all the technical wrinkles to make that happen!
* All base game scenarios from CMANO are being updated to add support for new features and generally improve them in CMO.
* CMO uses a new file format so while you can load up CMANO scenarios on CMO, you wont be able to take CMO scenarios back to CMANO.
* There will be a significant incentive for players who want to upgrade from CMANO to CMO, so you will not be paying the full price if you already own CMANO. Details TBD.
