I've posted a few times asking for info, personally I don't care which method they chose. Only that info on how it would work was posted.
So before the deluge of pro v con, I'll just say thanks Lilith, transparency is paramount when dealing with things as big as a merge.
I'd say that the cat is out of the bag however, and you'd be better served just posting a list of what servers are potentially merging with each other. So players can begin scouting each other.
