You have to be joking don't you....I mean if you have time to worry about the rego of the aircraft you possibly need to get out a little more!
The Dubai airshow is all about networking and getting into as many Chalet's as you can pretending to be interested in aviation and drinking all the "complimetary's" you can in a 15 miute window
Of course the 380 will be there, at least 3 airlines within a 150nm radius of Dubai have bought it and it is behind schedule...its all about "keeping up appearances"!
See you at the Airbus tent for a wee Chard or 6!
