Does anyone know if BA has plans to retire the old and tired 747-400 on the YVR-LHR-YVR route with something new in the near future?

I typically fly 4-5 times a year on this route in their W+. Must say that I am getting really fed up and sick of its granite hard seat and the miserable fuzzy 4 inch screen (not forgetting the not so attractive fares on W+). Overall, a very poor value.

Thanks.
