I'm also hoping for thinner bezels as the current models' ones are just huge compared to Dell's XPS line for example. It's slowly becoming obvious that the design has barely changed since 2016 or so. The 16" model was a step in the right direction, but it's still not even close to what Dell is delivering.
It'd be amazing if they managed to squeeze a 13" screen into the old 12" form factor - you'd still get great battery life thanks to the M1.
It seems like Apple is capable of it—look at the bezels on a new iPhone or iPad. But it would certainly require a whole new shell, which probably takes a while for Apple to design and ramp up because of all the machining involved.
