As others have mentioned, I find it unlikely that Honda will invest in a significant update to the Civic coupe until the next Civic arrives or a re-Mid-Model-Refresh down the road.
Why? The coupe for 2012 was actually pretty solid design, if not a little conservative and simple...which is a formula that works and why I liked it. It was sleek, understated, but still easily one of the best side profile looks on a coupe of this segment. Additionally, coupes sell in FAR fewer numbers than sedans do, so it made sense for Honda to put the majority of the amount of money dedicated to the refresh to the sedan. They stood more to lose if they didn't knock the 2013 sedan out of the ballpark.
Given the costs associated with this (which I've read were QUITE high), I doubt there's much money left in the Civic budget for any updates outside of maybe new taillights or trim pieces or chrome going forward. Given the Civic coupe got absolutely nothing different on the exterior for 2013 besides the cleared turn signals and the new wheels (correct me if I'm wrong), we might see a few aesthetic updates to it, but I wouldn't expect a whole lot, if at all. New grilles and taillight design seem the most likely update.
I actually just traded in my 2012 Si coupe for a 2013 Si sedan - the updates to the sedan were great enough to me to get rid of the coupe - and I am almost an exclusively two-door kinda guy. While I admired the 2012 coupe for its simple sophistication and sleek sportiness, the sedan looked too high end to pass up.
I don't think the two door looks bad - not at all, considering I owned two of them - but I do think it does look a bit plain: which some people like. MotorTrend had this to say:
