I've got a question. If Singapore does not like heavy maintenance and gets rid of their aircraft at around the 10 year point when heavy maintenance comes due, owning the airplane makes little or no sense unless they can be assured they can sell the airplane at the 10 year point. So why would Singapore replace 5 leased airplanes with 5 owned airplanes if in 10 years they won't be able to sell them? Especially considering that at that point the design will be 20 years old and even more obsolete than the 10 year old airplanes they are getting rid of.
