I do not think they would be able to "sort it out". Lets take the bigger parties like say DA, IFP, FF+, ID. And a crucial policy like BEE/AA.
As far as I know, IFP is in favour of it, just that Koosie says it must be implemented "fairely", the DA is sort of confusing one on AA, IMO they are saying "Jah, we know it is necessary, but not in its current form, they want it class based (the last I heard), which when you think of it, it is the same thing. Then you have FF+, who I believe say it should be scrapped all together.
Sounds they would need another CODESA to figure out amongst themselves what they want.
