The arrival of ETOPS, the focus on airline cost-efficiency and the arrival of larger twin-engine planes (777/A350) have really decimated the market for large 4-engine airliners. It is also destroying the market value for used A340s as well.
It makes sense though. Engine maintenance is something like 50% of the cost of maintaining an aircraft. When you can halve the number of engines, you can take a big chunk out of those costs. That's not to mention that twin-engine airliners are more fuel efficient and easier to fill with passengers than the large 747s and A380s.
The only airline that seems to be keeping up with 4-engine airliners is Emirates. It works for their operation of the superhub at Dubai and the fact that they get a lot of feed from slot restricted airports like Heathrow. Even old 747 stalwarts like Lufthansa and British Airways don't seem to have much interest either.
