I don't think things will be that bad. Microsoft made several moves recently - bought GitHub, started Linux subsystem project, all these projects with Android launchers, free iPhone software. What for? How are they going to make it profitable? They are making money on their cloud services, Office and new PCs with Windows 10. Xbox is the second source of money.
But there are lots of studios more commercially succesful, more convenient than inXile and Obsidian. But both have their own reputation - like GitHub they are full of talent and it is what Microsoft under Nadella is searching for. If I am right. Obsidian don't lose much - new Black Isle was founded, if things get bad they can open new studio. We will back on KickStarter.
