I think that evolution of humans from this point forward will not be due to natural selection, but through recombinant DNA methods.
First we will learn how to detect and remove the gene mutations that cause hereditary diseases. People will no longer get Cystic Fibrosis, Huntington's disease or Tay Sachs.
In the next phase, genes will be identified that PREDISPOSE us to common diseases of aging, for example heart disease. There is a protein in long lived people that prevents atherosclerosis by making more high density lipoprotein (good cholesterol). It may be that this is done through DNA transfers to an isolated egg cell or to sperm cells, or it may be done through cloning with modification. Another strategy might involve adding promotors that improve the expression of existing genes. Possibly multiple copies of genes might be made.
Another prospect might be borrowing genes from other species. It might be possible to transfer the gene for Vitamin C synthesis so we no longer need a supplement.
We might transfer the gene for telomerase so that our cells will take longer to reach senescense and we might live to 200 years of age.
The final phase, which is very far off, will involve creating entirely new genes.
