Fancourt is a golf course, so I assume they could make the venue as large or as small as they would like. Unfortunately it is not situated close to any major cities, Cape Town being the closest around 200km away. No idea how the ticket sales are going but I would be surprised if there are more then 10 000 people there. I say that because the 46664 Cape Town concert did not sell out (there were about 40 000 in attendence) and that concert had a much stronger overall line-up.
