They may have something to come, but realistically they're not going to admit it are they.
However, they still have engine problems for Alonso. The current motor has been in there since Singapore and still needs to do 3 more GP's.
Fernando ran "engine 8" at Italy, Singapore and Japan. He won't need to use this one again.
He has "engine 6" which has been used at Germany and Hungary. He will use this one more time.
He has "engine 7" which was only used in Belgium. He could use that twice more.
He has "engine 1" which he changed before the start of Bahrain so it hasn't actually been used in a race. The way the rules work, he also has an option to use that one at Abu Dahbi.
Basically, he's got plenty of engine options.
BTW HD, finally got to watch the the last half of Bathurst

but it took until yesterday for me to get it!
