Two people commented on the issue and that they question why it hadn't been done yet. I provided a possible reason. A reason also possible for why they won't do it if it turns out they don't.
You've got to be kidding me. RBY on VC are the highest grossing eShop titles ever. It's pure profit, and from an eShop standpoint, it's huge. Extremely low cost, and a higher reward than anything else on the entire eShop. And your claim that they don't see that it's worth it is not only baseless, but most likely wrong. That's like saying it's not worth bending over to pick up a stray $100 bill.
GF. Don't. Make. Spin. Off. Games.
We don't know yet. Since the previous consoles and handhelds could communicate, I will not be surprised if you are able to trade from 3DS to Switch and vice versa .
I could actually see them using a special accessory for this. They've done it before with spin-off games, and it worked well. Doing it for a main series game would be a major selling point for those who have the portable games, and wouldn't detract anything from those who don't.
I think an accessory may cause a blacklash among 3DS owners.
There is no evidence.
That's only been true when they're same generation. The GB/GBC and N64, the GBA and GC, the DS and Wii, and the 3DS and Wii U can communicate with each other, but those devices were same generation devices introduced all around the same time, which the 3DS and Switch aren't. The only way cross gen devices could communicate with each other in the past was through BC, which the Switch lacks. If we're going on precedence here odds are actually that the 3DS and Switch can't communicate, as that would be more like the Wii U being able to communicate with the DS.
That is a terrible comparison. Nintendo DS was dead before Wii U was even released, so of course those systems couldn't communicate. That situation is vastly different to now, when Nintendo 3DS is still well and truly alive during the release of Switch. Nintendo 3DS still has a good year or two left, so there is no reason why Nintendo shouldn't have made communications between the two consoles available.
Yes. Pokemon Stadium and its sequel. Nintendo fixed that later on by intentionally designing both handheld and console to communicate directly. Something that, as far as we know, hasn't been done with the Switch and 3DS family.
Okay, first of all, how do you know the 3DS has a year or two left? You're not Nintendo, you don't know for certain how long the 3DS has left. Second, whether or not the system is dead isn't as relevant as whether or not it's technically possible. But if you're that concerned about the system being "dead", a better example for that would be DS and GC. The DS was on the market for 2 years with the GC and could they communicate? Nope.
It's PR, of course Nintendo's not going to say they're dropping the 3DS. They want the system to keep selling until its natural death. That doesn't mean that the 3DS has a long term future and it's going to be compatible with the Switch. "Support" could mean a couple of B or C tier games and some lingering third party releases, it doesn't necessarily mean that the 3DS is going to remain on the market. They claimed the DS was a third pillar just like they did with the Switch and look what happened, the GBA was dead within a year and the GC soon followed.
3 console generations of that same pattern begs to differ. There's more historical precedence going against 3DS/Switch communication than for it regardless.
