It very much depends on whether or not there is new hardware in the Switch Pro that can run games at Native 1080p. If there is a new SoC that can allow games to hit that, then I would like to have the option to run the games at 1080p or 720p instead of having Nintendo making the choice for me. But if there isn't a new SoC or the games can't hit the Native 1080p resolution, then I'd rather just have the 720p option as running at Native 720p on a 720p screen is better than upscaling 720p game to 1080p.
