The ambiguity about if physical releases are included here is annoying but I'm still pretty happy about this.  I felt like this was a litmus test if Nintendo had gone off the deep end or not.  If they didn't have it all that would not bode well for the Switch successor.  Nintendo can do really strange things but this is something very conventional and if the Switch 2 can play Switch 1 games then you know the Switch 2 is still somewhat of a conventional video game system.  I think of how Nintendo really pushed the 3D aspect of the 3DS and that didn't really catch on but the guts of the DS were still in there so it still worked well as DS successor even if it's big gimmick didn't take the world by storm.

But there was a part of the briefing that isn't as notable but combined with this makes me feel quite confident in the Switch 2.  Nintendo emphasized their third party relationships.  I love my Switch but my library is not predominantly first party.  Now that Nintendo has great third party support again, my library more closely resembles what my SNES library looked like with a lot of third party games and Nintendo having no real prominence over other publishers.  So I'm glad that they regard third party support as important and as something to maintain with the Switch successor.  And third party support plus backwards compatibility means that the Switch 2 is not going to be some insane wacky system that misses why the Switch was successful.

Though I really want physical backwards compatibility and I'm a little on edge until that's confirmed.  But they very well may have a digital-only model and a physical model, following current trends.  It would seem odd for them to have a version that supports physical media but then have it be completely incompatible with existing Switch carts.  Just to maintain the portable nature of the system you figure they would stick with the carts.  They're not going to switch to optical discs or anything like that.
