It definitely shouldn't come as a surprise to anyone, and should be the obvious choice to make on Nintendo's side too... But it's probably worth noting that it's Nintendo we're talking about, and the games industry as a whole. They have a tendency to make questionable decisions that people could immediately tell were questionable decisions, either for anti consumer reasons or just not knowing the market. So while the odds of the Switch 2 being backwards compatible were really high, and we all knew it was the obvious choice to make, there was still always a worry that it wouldn't happen for some ridiculous reason or another.
