Don't hold your breath. There were never going to be price decreases as a direct result of " free peering". MWEB did a great selling job to convince people they're doing all of this for the "benefit" of SA consumers.
It's good to see the big boys are now peering locally again (i.e. they're just back where they were before MWEB's actions), but what about all the smaller ISP's who cannot afford to peer directly with MWEB and used to peer via SAIX? Are their subscribers condemned to perpetual cr@p latencies?
I have said a number of times that if MWeb were successful they should put their money where there mouth is. I don't think that this will ever happen. They have played these lists to the T. An absolute PR scam if you ask me.
Nice that performance will be better but the principal is questionable.
