Why waiting in vain? No release date was ever mentioned. Only that they were working on them. Release to stores will likely be late summer or fall of 2015 unless issues develop in which case it might be pushed into 2016. Release will be at the same time as the FF camera body so release date will depend not only on the lens development but on the camera as well. And since any FF body will also need a 24-70, that lens must be in development also.
So nothing will be seen until FF body, 24-70, 70-200 and 100-400 are all complete. We can also wish for a 14-24 but I think that will come later.
