The Air form factor is already pushing the limit of what you can do with aluminium and still have high confidence it won't warp when you shove it into your bag, or have it fall over when you open the screen past vertical.
I could see them slimming down the battery to get more components in, maybe, rather than two day battery life.
Which would probably be the right call. There just aren't enough circumstances where not plugging in your laptop while sleeping is necessary to justify it.
Personally I'd like them to make a model with a cellular modem, with all-day battery life even reasonably far from a tower. That would be fun.
I'd expect carbon fiber reinforcement to add stiffness soon on some of these larger, ultra-slim devices. That's what we use for sports equipment, and CF+Al bonding is a well solved problem in manufacture.
