Good news indeed and hope it is a great success.
Personally doesn't help a lot as our regular flight to YVR from LHR departs at 1710, so however you look at it a long wait at LHR, Possibly more usable on the way back though. That said the big advantage is no luggage to hump around at LHR and perhaps some decent connecting fares so that wait enjoying the galleries lounge may be worth it after all.
