I bet they are already working from quite some time. But I think we will not see any changes at the top until the 8000 series will be launched. A dual GK104, rumored to be in the works for May launch, based on what's capable this GPU will probably best the 7990.
The interesting part is what comes next lower down the Kepler line. GK106 is nowhere to be heard of so I expect NV will give us another 2 GPU's based on GK104, one to target price/perf of the 7950 and one for the 7870.
