Death of the GXR project?

They actually did that when they first launched the GXR by displaying a plethora of different modules from remote camera to a printer etc to show off the possibilities of this new system.

None of which have ever came to pass, so they possibly learned not to do that any more after fending off all the "so where's that projector module then?" questions over the intervening three years.

So the 2013 GRD is obviously already in the works, so they can confidently put that placard up for it!
