I'll want to buy a Switch 2 if Nintendo does this the next day.

Based on the information provided in the text, it seems that the author is eagerly anticipating a future Switch model (referred to as "Switch 2") with several key features: 1. Improved Joy-Con controllers, likely with haptic feedback sensors. 2. NVIDIA hardware support for DLSS (Deep Learning Super Sampling) to enhance visual effects. 3. Backward compatibility with existing Switch games and accessories. The author expresses willingness to purchase the new model if it meets these criteria, particularly if it includes backward compatibility and supports advanced graphics features like DLSS. They also mention being open to additional Joy-Con alternatives if the built-in ones are not satisfactory. While the author is excited about potential improvements, they also note that the current Joy-Cons are considered a weakness of the Switch console. They express hope that Nintendo will address this in future iterations of the hardware. The text suggests that the author has been following developments in the Switch ecosystem and is eager to see what Nintendo will bring to the market with their next major update to the platform.
