Nintendo Switch 2 will be backwards compatible, leak claims | Eurogamer.net:

That's according to Universo Nintendo, a Portuguese website that claims the Switch 2 will not only have backwards compatibility with Switch titles currently available on Nintendo's handheld system, but developers will also be able to "enhance" these games thanks to the additional processing power.

As someone with a goodly number of physical Switch games, I find myself enthusiastic about these rumours. Where I remain skeptical however is in the SoC department.

We’ve seen Apple pushing the power of their mobile SoC with the release of Death Stranding on the iPhone, do we really expect NVIDIA (and the traditionally reserved Nintendo) to have cooked up something on that level? Gosh it’d be fun!
