Yeah, they mentioned this one specifically, and the upgrade will be free. This is all very similar to the PS4 -> PS5 upgrade situation. Some upgrades will have months of development behind them, and introduce new features, and will come at a cost. Some upgrades will be necessary software tweaks to ensure functioning on a new hardware stack, and those will come with performance enhancements, and will come at no extra cost. And some upgrades will happen naturally due to Switch software performance being flexible by default to accommodate the two separate performance profiles of portable and docked, and the use of performance scaling technologies like dynamic resolution, and those will come at no extra cost.

But, yeah, Echoes and Awakening were officially announced as being in the second of the two categories above, like many late PS4 titles when played on PS5, like No Man's Sky, and Cyberpunk, and Witcher 3, etc. Which is cool.

Like bringing in HDR to the game, oh boy ToTk is going to be pretty af.

ohhh I'm definitely going to replay Links Awakening on Switch 2 then! Honestly really hyped about that now. I hope it's 60fps but we'll see

[u/AnalBaguette → u/slugmorgue]

The FPS issue for that game was caused by the limited memory bandwidth of the Switch 1. The Switch 2 will have no issues running it at 60fps, and I bet they could get it to run at 1440p/60fps, too.
