You can end up with everything and anything, and the same matings can produce very different litters next time
Quick caveat, you can end up with them all looking like one or other parent, so mixing doesn't always throw up interest.
It changes every time, so below is just an idea
OSB to saddleback -we had a perfect saddleback in one litter, except she was ginger and white! Quite often get tri-colours with large spodges of black dots on a ginger and white background, very pretty pigs.
OSB to GOS - again can throw anything, but quite often you get very spotty pigs - see last picture on our "for sale" page to see a litter of OSBxGOS

But it is a gamble/great fun to see what you get
