Being a reasonably regular traveler on this route, I believe the 767's are due to be pulled from that route mid-summer (can't precisely remember whether it's 30 June or 31 July). They'll be replaced with the 787's - with the more crampt seats.
I have mixed feelings as I've used this route frequently since 1996 (sufficient that they know me in the lounge!) - probably the same aircraft (certainly type) over these 20 years, but they are showing their age. While the 787's will provide a new feel, the packing in of passengers won't be too welcome since I'm usually in Y. That said, but first trip on this route in a 787 will be in CW :-)
