Update: Nov. 12, 2014
You can listen to Nicolas Harnoncourt's lecture on the Bruckner manuscript here, where he plays only what Bruckner lived to compose (which is 90% of the movement, with only an indication of what he wanted for the Coda, and some woodwind instrumentation not completed)
Most versions (since around 1990) provide a complex coda. The first part of the coda is a massive fugue on the "octave theme" of the first movement. (This sounds like true coda to me, not recapitulation, which has already happened with the majestic cathedral theme.) The music comes to another cathartic on huge brass dissonances. Then there is a "coda of the coda" where Bruckner, having concluded the Ninth formally speaking, wanted to summarize a lot of his earlier symphonies, tracing them back to Beethoven, in about 4 minutes of cathedral-like triumph. The versions offered seem to take the descending fifth's theme from the Third ("Wagner Symphony", also in D Minor), superimose some of Wagner's Ring, which mixes with the rising theme that opens Bruckner's own Seventh (after all), and then blatantly superimpose the opening "fifths" theme of the Beethoven Ninth and the famous rhythm that opens the Beethoven Fifth. It's as if all of western symphonic music could be summarized in three minutes, maybe at a celebration of the anniversary of the fall of the Berlin Wall now. The music finally crashes "FFF" on one tremendous D Major Triad in the brass and full orchestra.
Above I've embedded the last ten minutes that I like the best, the 2008 Samale-Phillips-Cohrs-Mazzuca Reconstruction, which is what I would recommend be performed now. Maybe we will see it in NYC or Washington in the 2015-2016 season.
