Yes, CX278/279 will resume as 3 weekly in January with adjusted timing. Currently the A340 sits in CDG for more than 12 hours. When it resumes in January 2015 as a 77G and they won't let it sit in CDG for that long.
They would probably make it back to maybe daily again during summer 2015 depending of 77G availability.
