I don't know on what basis people have decided BC doesn't extend to physical copies? Is it because they announced BC and continuation of Switch Online at the same time?
I don't think there's anything more recent than that comment of any substance, so not sure why people have decided it's physical only.
If anything, the sentence 'its compatibility with Nintendo Switch' hints at potentially even supporting inter-generation backwards compatibility - i.e. if you played MK8 on your Switch 2, you could play online with people playing on Switch 1 still.
This is Furukawa. At today's Corporate Management Policy Briefing, we announced that Nintendo Switch software will also be playable on the successor to Nintendo Switch. Nintendo Switch Online will be available on the successor to Nintendo Switch as well. Further information about the successor to Nintendo Switch, including its compatibility with Nintendo Switch, will be announced at a later date.
