It might even be able to carry some cargo! But still, the 77L does burn up the same amount of gas the 77W with much less people. Its been rumoured SQ will be the next or one of the next 777X customers. The ME3 have ordered both the 777-8X and 777-9X. The 777-9X will have the range to do SFO-SIN under a normal layout. LAX-SIN would require restrictions and EWR-SIN not possible. The 777-8X will be closer to a 77W size than the Worldliner and already has a planned range of an astounding 11,000 miles. It can do EWR-SIN in a normal configuration, although not sure who would want to do EWR-SIN in Y. If its all J again, it can carry more in J this time and definitely some cargo. LAX-SIN can be done with a full load, at a much cheaper cost than flying a fuel tanker. The reason why the 777-8X will outsell the Worldliner is its much bigger, making ultra-ultra long flying cheaper. I'd be very surprised if SQ doesn't buy both variants of the 777X by decade's end.
