Don't forget that MoL has been on record as stating that he was against LH as the pilots would see it as a holiday and that he would not pay them to have a party down route.
The last time this subject was debated in PPRuNe, I gave the quote with chapter and verse but cannot find it now. I would take a small wager that it will be done by MoL's successor. Afterall, that person will want to make their own splash and pot of money. Which, of course, is a very good reason for MoL to stay on and do it!
