"I know that the flaps are going to be single slotted which should be somewhat boring compared to the 747"
But also weigh far less and make much less noise on approach, to ensure it meets ICAO Stage 4 noise restriction regulations. If it can use a single slotted system to achieve the required delta CL
on take off and approach, I don't see why "boring" would have anything to do with ensuring the aircraft performs.
As for the landing gear, I haven't really had a look but I would expect 6 wheel main under-fuselage bogies, 4 wheel bogies under the wings and a large 2 wheel bogie up front. The A380 is supposed to spread the pressure of its enormous landing weight out over an area such that it has less impact on runways than the 747. Whether this is achieved remains to be seen, and in any case many airports will have to upgrade taxiways, filletting etc. not to mention terminal facilities to ensure the A380 can operate effectively.
