Xenoblade deserved to do better.

Many games do...... Many games do :-/

Japanese people don't really like JRPGs. They like FF and DQ.

Anything that doesn't have an established name is not going to push amazing numbers.

Yo-kai Watch didn't even sell that well at first and only started selling after the anime took off. You'd see better sales of Nintendo's more obscure franchises if they invested more in cross-media projects. Although truth to be told, such investments aren't wise for a Wii U game.

We do need Zelda, Metroid, Pikmin, xenoblade animes in the future though. Only then can these franchises grow.

It sold 6% for that month. The charts aren't lifetime digital/physical sales.

Edit: You also cherry picked his statement. This is the entire thing:

3. This digital sales come from a monthly retail and digital Top 30 Ranking. That means that if the game doesn't chart in that ranking, there's no way to know its digital sales. So, a game can sell decently digital, but if it doesn't reach the 30 position in that ranking, there's no way to know how well or bad is selling digital. So, we should consider this numbers as the minimum digital sales, instead of a total sales.

If we assume a 10%-15% increase in sales for Xenoblade X over the first game, in all regions, then we can expect it to be more or less a million seller. For a "traditional" Japanese Role Playing Game that isn't Final Fantasy, Dragon Quest, Kingdom Hearts, or Pokemon that is pretty good.

I'd be happy with numbers close to Tales of Xillia or Bravely Default (slightly over 1 million) and satisfied with 900k - 1 million lifetime.   

It also depends on the budget of the game though. I don't think there  is/will be a huge marketing budget so that will save a lot of money. They also mentioned multiple times that they were constrained by time/budget so we can expect the game's development budget to be relatively modest. If it is something like 20 million to produce, localize, and manufacturer the game, and the game sells 10% digitally, and it sells like 1 million,  then we can probably expect profits to go something like this, without regarding regional taxes: 

100k*$60 (digital) + 900k*$45 (retail) - $20,000,000 (costs) = $26.5 million. (Nintendo games don't ever really decrease in price, so almost all copies should be sold at $60 and $45 profits.) 

That is enough for Nintendo to fund Monolith Soft's developement of another RPG, assuming development costs marginally increase over Xenoblade Chronicles X, and Nintendo doesn't have something else in mind for Monolith Soft. That would be good. 

#9 on Media Create.  Last game opened at 16k.  I was hoping for better.

I would think digital sales would be pretty frontloaded, as they appeal greatly to people who are impatient and want to get the game without having to travel to the store (maybe that is one reason why Japanese digital sales are less - higher store to people density.) Still I can't reconcile low Japanese digital rates, at about 2-6% for Nintendo games according to Famitsu, while Nintendo claims Japanese digital sales (after dropping) make up 30% of total digital sales and then also claims that their digital sales make up 13% of total sales in NA , especially when Japanese sales usually are less than NA/European sales overall. 

This means Japanese digital sell-through rates (for Nintendo) must be close or larger than NA/EU because they are selling almost a third of all digital games, while selling fewer total games in general than the other regions. 

The full quote doesn't change much. In fact it enhances my point.

"if it doesn't reach the 30 position in that ranking, there's no way to know how well or bad is selling digital." 

So a game could have a digital rate >10%, but if its overall sales aren't that great with respect to other games we won't know about it. 

I expected less for Xenoblade X, considering lower pre-orders on comg than Xenoblade Chronicles.
Also, does the DraQue expansion include the original game ? Because that mean the Wii U expansion sold almost half of the original game, that's a pretty good ratio I think ?

Sure, but the virtual console and DLC games are released in all regions. They are a constant. Unless you believe they sell more in Japan than in other regions? The ratios still remain the same, in such a scenario. 

The same holds true for the 3DS by the way. You are only given a 4 GB SD card with most 3DS purchases. Two or three 3DS games fill this up pretty fast. For the price of a class 10 32 GB SD card you can get a 320 GB External HDD.
