Just a crazy and rough guess tbh, considering Samsung S5 will be released with "only" a 1080p OLED screen and, afaik, no device with 1440p OLED have been announced.
It will take 4 months for them to deliver this dk2, if 2014 is unlikely (as it says in OP) and the massproduction of 1440p displays not in effect for at least a good while ahead, I can't see it coming "very shortly" after dk2.
Just some rough speculation, I'm probably wrong on many levels and feel free to oppose or even ignore my guess 

Pre-ordered dk2 for my first VR experience anyway and I'm looking forward to CV1.
Edit:
Yeah, seems like they might have a bit of a different plan now, since they state that CV1 will get a pretty good update? 
With the upgraded resolution, latency and all.
