Jorg: The World Update 3 delay was because of London’s photogrammetry. Something was not quite right, and we think that the problem was a data processing problem. We plan to revisit London photogrammetry in the future. Also, there was a very high vertices count in the London photogrammetry, and Asobo has written a script to reduce that in order to get better framerates.
Sadly we are still waiting over 2 years later!
