Oh for sure. The main question in my mind at this point is "Is it worth it financially?"
Like do they envision themselves generating enough additional software sales for it to be worth $30 less per unit on the premium device, which is the one that likely attracts premium buyers more than budget buyers.
It would probably incentivize upgrade sales, but those are only useful if they actually make money on it, since it's not a 100% obvious increase to the amount of software being sold in the same way a new customer is.
I guess my main mindset is that this kind of stuff makes a bunch of sense in the front end of the generation when prices are pretty high, but once you have some pretty accessible options late-gen, it might make more sense to just focus on being a profitable company instead of driving an install base you might not be selling to for year on end.
Well, I'm proposing such an idea because it's something that they're actually doing it...in Japan, best 3DS territory by far. And, for June selection, there's even a title that will be released right in June (Pokémon Art Academy), among older titles. So, they're already giving up on part of their hardware revenue in order to let stay hardware sales on a good level over there. Moreover, the Recommendation Selection concept is actually something that IMHO is perfect for consoles around the 3rd / 4th year in the market: the software selection is big enough to have titles eligible for the selection, titles with still sales potential and old enough to not have an excessive negative impact on revenue, there are late customers who would love to get a console with many titles for cheap and, above all, games for cheap. Especially if you have different SKUs of the console: in 3DS case, the initiative would start for 3DS XL, while 2DS price would still be 129.99, as entry price for children. Making the console interesting enough for sales to not fall off a cliff even in later years is also often said to be proactive to assure the successor to that console can benefit from a base momentum, given by the older console. It's true that I think such a thought is overstated sometimes (Wii after GC, 360 after Xbox...or PS3 after PS2 in the opposite sense i.e. there are many other factors influencing momentum), but it's also true that it shouldn't be underestimated too much, especially if the successor doesn't represent a revolution compared to the past, like the Wii.
Still, I think the Western counterpart wouldn't go as far as actually giving away yet-to-be-released games, like happening in Japan, that's for sure.
I think the eShop also makes a lot of sense in that it prepares them for a digital future, which is one of their best bets to increase margin and deal with any shelf space issues if the market takes a turn for the worse.
Beyond that, yeah there are definitely still levers they can pull, but I think it's more about floating it as best they can without notable financial harm to themselves or to their future platforms.
Considering how eShop revenue increased a lot last year again, I think they will continue investing there, so no need to worry on that front
