Yes, we have seen the switch already taking place, as Sami describes. The big boys are concentrating on ordering efficient and new planes. The used market is being refreshed at random between 0.5 to 2.5 (if I recall correctly). It is in fact a matter of timing to be successful on the used market. I was very lucky a couple of time, but generally managed to get a total of 24 used a/c with SAME engines, in order to keep up fleet commonality this early. Also, I had one competitor going bankrupt just yesterday and he restarted, flying 6 used (although very old) B727-200s and DC-9s. I was astonished about that quick move.
Generally, I like the pace of the game and I love the highly competitive nature of it! As said before, the often observed overcrowding and straight ordering in past games has made it easy to determine early on who might dominate. This time, it is an absolutely different setup and it become even more challenging, as the unknown moves of setting up further bases comes into effect during the next game year.
If anybody is having trouble with strategy and setup, please feel free to discuss with me via message, I am eager to help those struggling.
