You misquoted the article or the article changed since you read it , what it says now is;
"There is currently no aircraft in the Malaysia Airlines fleet which could replace the A380."
Note the currently part of the quote.
I believe their B772ER has the range, but the seating config is bad and many of the planes are getting old.
If MH are going to get rid of the A380 they must either upgrade some of the B772ER with new cabin configs or buy new planes or both.
B787, B777X, A350 or A330NEO are all options for newer and more fuel efficient planes, but unless MH has some on order I think the wait might be long for most of these.
If I remember correctly there are some early model B787 aka the terrible teens that that have not been delivered and is sitting and waiting to be sold. But I seem to have read that they are heavier than normal B787's so might not have the range.
Also I think there is still a hole in the order book for 2017 model of the B777, did not United just ordered some cheap like 50% of list price? Will get some of upgrades that are going in to the B777X so from 3-5% lower fuel burn than a 2015 model B777.
Not as good as a B789 or A350, but far better than what MH has today with lower fuel burn and cheap purchase price.
Bonus of having the same type rating as much of their current fleet so they already have plenty of pilot's and other crew trained.
