Following the purchase of Kyalami by Toby Venter a series of significant upgrades have been announced including some layout changes. These involve the extension of the main straight (with a kink in the middle) to 900 metres in length, and some corner changes. You can see the old layout in pale grey in the aeriel view pic in the article linked below.
There are multiple infrastructure upgrades as well, and the intention is to get the circuit to FIA Grade 2 standard. Presumably the intention will be to attract some sort of international racing at some point in the not too distant future.
Good news!

Here is a simulation of the new layout with a virtual 962 taking some weird lines...
