From a local ham I've heard that all disagreements have been resolved and there is talk about the three sites merging to some level to help reduce hosting costs and such. Because of some amateur not liking the merge initially, the sites will for the most part be kept separate. But the necessity to exist due to rough economic times pretty much mandated this move.
I am not sure when the official announcement will be as my source did not know either. However, you may start to notice some similarities among the three sites. You've likely already seen the QRZ database being used on eham, and the old HamSexy rival site to QRZ link directly to QRZ.
I will post more information as I receive it.
