You can read about it in detail here. A few of the things that were predicted would be that the cosmic background radiation would be highly uniform and a perfect blackbody, that there would be an abundance of light elements early in the universe, and that the universe would exhibit large-scale homogeneity.

There is an exciting new generation of technology on the way which should increase our knowledge further. The James Webb space telescope will be many times more powerful than Hubble and will hopefully help us to see some of the first stars and galaxies. The cosmic microwave background will be measured in even more detail; there will be large-scale surveys of galaxy distributions and supernovae; and the Large Hadron Collider goes on line next month.
