i don’t think it makes sense to have a new generation that has no single part compatible with the current one because the current one doesn’t really have specific flaws overall that can’t be addressed by a new part, and so far it has happened (top cover, speakers, hinges).

personally i don’t even think the fw13 has saturated the customisation possibilities (new screens, ARM, etc.), which probably says more about how boring the laptop world has become, rather than fw’s limitations.

it’s not exactly the same though, which is what matters if you want to make parts compatible
