Whatever happens in the future airlink have not really grown in the last 4 years. Ok you have the jungle jets replacing the J41 on a few routes out of FACT and a few flights north of the Limpopo and Zambezi but not that much. I recall a few years ago they ordered 30 ERJ135s.
This article from 2001 alludes to another 28 aircraft and was written after the first two were delivered.

By the way are they still planning on phasing out the J41s as was once mooted?
