Yeah, I didn't get to chose the names :)

For all we know, so far, allwinner has released, by family:
  - sun3i (ARM926)
    * F20 (not supported)
  - sun4i (Cortex A8)
    * A10
  - sun5i (Cortex A8)
    * A10s
    * A13
  - sun6i (4 * Cortex A7)
    * A31
    * A31s (not supported)
  - sun7i (2 * Cortex A7)
    * A20
    * A23? (that was just announced)

So yes, even though they are quite close, A10 != A10s :)
