Per Frank Seravalli, who once leaked an entire expansion draft but now gets few trade details, the Patrick Kane trade details are emerging. It looks like no roster players or prospects will be going to the Blackhawks.
Assuming the above is correct, then the Rangers will sacrifice 2nd and 4th round picks to Chicago for Kane. Per Emily Kaplan, the 2023 2nd becomes a 2024 or 2025 1st round pick if the Rangers make the Eastern Conference Final. This means, no matter what, the Rangers have a 1st round pick for the loaded 2023 draft.
