Today an interview was published with Philippe Lavoué From Nintendo France
Here some infos from the interview:
Wii U: ~150K YTD, ~450K LTD
Mario Kart 8: ~272K (~200K+~72K Wii U bundles)
Pokemon ORAS: ~191K ("~50% better than last entry in the same number of days)
Last Week: 3DS sales got an increase of ~70% due to Pokemon ORAS.
Some estimates from him:
~550K WiiU end of year; ~200K SSBU; ~200K Amiibos

VGC DATA For Wii U: 175.1K YTD; 467.9K LTD (also note that there isn't data for 29th on VGC yet)
So hardware was kinda overtracked but that was expected since many consoles are overtracked in France (overall gen8 home+handheld was ~150K+ overtracked from January-September in France). At least MK8 isn't ;)
Prediction: End of 2015 Hardware sales (as of January 20, 2015)
Wii U: 12.1M | XBO: 19.8M | PS4: 36.0M | 3DS: 58.5M | PSV: 11.7M
