As I said in the Week 50 thread, I think 270k is pretty disappointing for what's supposed the biggest week of the year and it's all to blame on Nintendo's supply chain. It's a shame, because consumers young and old weren't able to pick one up for Christmas this way and publishers miss software sales this way. Since the Switch has good availability now in North America and Europe, I think Nintendo could've put more priority to Japan for December than they already did. That being said, overall December has been a good month for the Switch so far. Since the start of Week 49 (December 4), 655.802 Switch units have been sold and there's still a week left. Hopefully sales stay above 200k next week.
As a result of bigger hardware sales, software sales have gone up too. Most games see bigger rises than the hardware itself tho (in units). Most first-party NSW games are at least 90% up, and ARMS and Pokkén even ~140%.
The 3DS games that were released this Fall continue to do well too. Kirby and Girls Mode 4 above 100k, Animal Crossing keeps selling, and the last Sumikko Gurashi 3DS game too. Pokémon USUM is at 1.985.852 now (almost 2M!)
Bandai Namco's late ports keep doing well. DBXV2 is back and will most likely pass 100k next year. I didn't believe on beforehand that this would happen! One Piece: PW3 also has a nice opening for a late port of a 2 year old game (it is the best portable version and includes all DLC tho). With DBXV2, ARMS, Pokkén, and upcoming BlazBlue Cross Tag Battle, the Switch starts shaping up as a real portable fighting game machine, which I think is very cool! The same can be said for Musou-type games with all those ports and Fire Emblem Warriors. :P
Amazing how the Switch ports are (almost) outselling the original Wii U game!
The Idolm@ster and Atelier are disappointing tho... Stella Stage is doing less than 30% of previous games FW, and Atelier is reaching new depths. :( I was hoping to make a sales comparison between PS4 and NSW (and preferably PSV too), but I'm afraid we'll have to wait a couple of weeks (or worst case the CY 2017 overview).
Earth Defense Force 5 on the other hand is doing great! 250k physical+digital combined, as confirmed by D3 Publisher. 85.000 digital sales = 34% digital ratio, which is ridiculous tho. I assume it's 250k shipped to retailers.
As for PS4 hardware YoY with 2016, I'm afraid it isn't gonna make it. A drop next week WoW makes most sense, and as hiska-kun shows in his graph, the PS4 needs more 58k units. I'm afraid that's not gonna happen. At least it isn't a big decline.
Switch 2017 outselling the Wii U LTD will be very tricky too...
So yeah, this week has its awesome and less awesome bits. The biggest shame is Nintendo's hardware strategy. Every Switch unit sold is an improvement of course, but it's a shame that it's going at a lower pace than we're hoping for. Consumers and third-party publishers are the biggest victims here.
