I expect anything that falls under sun9i to be compatible, or a trimmed
down version. But that's just me.

We know that Allwinner has released the A33, which should be compatible
with the A23, sun8i. And the A83 has been announced, which looks like
a trimmed down version of the A80. The next SoC should be arm64, and
would not matter here.

Kevin, Shuge, could you provide us with the codenames for the A33 and
A83, and what earlier SoC they are based on?
