We don't have a plan extending as far as a year, so I just can't say.
However, if WebGL becomes widely supported and the Web Apps standard keeps progressing, I'm wondering if we'll need an EXE exporter at all. If C2 games are running with a hardware accelerated WebGL view complete with shaders, using javascript engines that are compiled to machine code and using the new Web Audio API for reliable audio with effects... what need is there for an EXE exporter?
