What disappoints me the most about this is that I know that there is almost no chance of Construct 2 editor having a Linux version. MMF2, GM8, and Construct 2 don't really have much to differentiate themselves in my mind. I was hoping that the Construct 2 rewrite would make it possible for someone to port the whole thing over the Linux, not just create an exporter or something like that.
But now, it just isn't possible. They aren't using Qt4 or any other cross platform libraries (afaik) in the editor, so porting will be very hard. And since this is no longer an open source project, and there's a huge focus on trying to compete with MMF2 and GM8, there's no way I see that Construct 2 will work towards differentiating itself in the manner I hoped it would. Instead, it'll probably work on trying to incorporate the features of MMF2 and GM8 to a level that people will find satisfactory, without losing the unique event-based system Construct 0.9x had. Probably, with that aim in mind, we may see a Mac OS X port years down the line, but there'll never be a Linux port...
