Australia makes up maybe a few percent of total sales and the walmart bundle you linked is over $500. MK8 bundles make up a very small amount of its sales, it's around ~23 million shipped and would at worst be like ~20 million without bundles.
Hence why I said "Bundle heavily in various regions". - They were examples.
The USA bundle includes more than just the game, hence it's price, it includes a steering wheel, carry case, extra Joycons.
But again... It was an example... And you are missing the point of why I provided such an example.
Either way. Here is another at a lower price:
Or hows about Target USA?
Here is another bundle, this time the UK.
Need me to continue? Those are all sales, they all add up. - It's still not going to account for 10's of millions of sales as the game has been on the market since 2014 and been selling since then, but it all still adds up.
Obviously Nintendo are at the point where they are happy to give the game away with a console.
Of course they arent new titles, I didn't say they were, I'm saying to the vast majority of people that does not matter because barely anyone owned a Wii U. They are highly desirable games that were stuck on a highly undesirable console and are selling as if they were new titles.
The amount of people who owned a Wii U is irrelevant.
Doesn't change the fact they are ports of old games, Nintendo is just making money with minimal effort. (And so they should if they can profit from it.)
But I would argue it's not pro-consumer when a game built from the ground up to take full advantage of the Switch's hardware could give us a brand new experience.
