Boeing recently put the stop to new 767-300 pax version rumors..They said that would require a parallel production line and that they decided not to put resources into that.

Plus the article above specifies A330 NEO's and the 787...I have recently been saying the best way to fix the 767-300 pay issue is to replace them with A330 Neo's
