Further to marni's post, MAG has also designated Pier 3 as the new home of MAN's A380 stands. This takes advantage of the additional manoeuvring space available between Pier 3 and Pier C. The road layout in that space has also been redesigned to accommodate the change, so it appears to be a solution for the long term. Whilst I haven't seen final confirmation, my expectation is that the Pier 4 shown in the early plans will never be constructed.
