It is no secret that Lumia Denim and Windows Phone 8.1.1 (or GDR1) is officially due for Lumia Windows Phones this month, overlapping into 2015. Still, for those in France who are also on SFR, there now appears to be an official schedule for said updates.

The SFR Denim program reveals which Lumias get the update first in December and which will carry over into January. In that sense, it is interesting to see which Lumias get first dibs on Denim. As it turns out, it looks like Microsoft is going for market share, as those Lumias that are newest and most popular appear to be the first to get the update.
