What could the Switch2 'Gimmick' be?

[Chrkeller]

After reading DF on Rebirth I want an optional pro dock more than ever. On a small screen resolution and fps isn't a concern, not the same on a big screen. Apparently Rebirth on the ps5 is barely higher than 1080p in performance mode (fps). Feels like an optional dock with horsepower increases could help with third party quality ports.
