The A380 will join the fleet in 2007. At that time, the satellite S3 with several gates dedicated to the A380 will be operational.
The biggest problem is not the A380. The biggest problem is if ADP has to destroy the whole Terminal 2E. Actually, they are talking about tearing down "just" the part that collapsed, the part with the boarding lounges and the jetways, not the WHOLE building where are located the Check-in areas, luggage delivery etc...Even though, if they decide to do so, it will take months and even years before they can re-build it as new (long) studies will have to be undertaken before starting the reconstruction...
Anyway, it is far too early to speculate on the future of the 2E.
Concerning the Traffic itself, 2E was just partially opened, and "only" 60 flights a day were treated at 2E. If 2E has to remain closed for several months, Terminal 2C is likely to become the temporary "Skyteam" terminal, some AF
flights will be redistributed to 2A and 2B and some airlines, recently moved from T1 to Terminal 2 will return to T1 just like Iberia, who had recently transferred its flights from CDG1 to CDG2, and who returned as soon as today to CDG1.
