I have also heard that MS are planning to control of 3rd party add-ons for MS Flight. Personally, I think this is a huge mistake. Because of that, I think that MS Flight will suffer from a lack of either sales, or 3rd party add-ons. Most likely the latter. A lot of developers might just decide it isn't worth the bother of doing add-ons for either, which would be a slap across the face for MS trying to be too controlling. It would serve them right too! It will probably also keep the interest in FSX for quite a while longer if MS are going to do that.
