Given the longevity goals with their modular designs, I'm guessing they're unlikely to make dramatic changes to their overall design in less than 5-7 years time from initial release. Such a screen change would likely require new hinge design as well as a thicker display casing, not to mention the risk of someone putting the trackpoint keyboard in a model that doesn't have the thicker display section.
I am thinking that something with a nub on a 2-axis slider as opposed to rocker switches could be an option, but that would potentially have drift issues. Not to mention the Framework keyboards themselves are probably mostly a COTS solution, where something like I'm thinking would require custom R&D an likely be limited release. If Framework, Dell and Lenovo could work together, they could probably come up with a good solution... though Lenovo likes the Fn button in the corner, where most others prefer Ctrl then Fn.
