They certainly can improve the Keyboard without a total redesign. Rumors are no full redesign until 2021, which makes sense. That doesn’t mean we won’t get an improved keyboard mechanism and maybe more USB C ports this year.
It would be very interesting to see what happens with the MacBook. It was an ambitious product that was way too ahead of its time. Chipsets that will make it a viable everyday machine won’t be around for a while. In the meantime, ARM would be a good way to dip their toes in the water, if they decide not to remove it from their lineup. ARM would also allow them to lower the cost.
You won’t see a new MBA until October or November, just because the suitable chips won’t be ready beforehand.
Obviously, I’ve very excited what IceLake and Tiger lake can bring to the MBA and to a lesser extent, even the MBP.

If this is true, there’s no chance we’ll see a 4 core MBA until late 2020.
