I think they are using the F.M.P indexes which means it should not take long for it to appear.
Apparently the cost of the index and images is £3,000,000 so most sites will charge extra to cover the costs if they host it.
I think TheGenealogist will bundle it with some other items to make the extra cost palatable.
Good chance that the Mormons could stuff everybody up by putting in on FamilySearch for free

Three million quid is chicken feed to them.
