Does God's foreknowledge contradict free will?

The 'God's foreknowledge contradicts free will, because we can't make God wrong' argument ONLY works if free will is something that exists within what you might call the 'three known causal categories'. The three known causal categories are: a) randomness, b) probability, and c) determinism. For a human the whole idea of a 'prediction' necessitates these categories. 0% certainty = randomness = no clue at all, 50% certainty = probability = it could go either way, 100% certainty = determinism = no chance of it not happening. We can never think outside of these known categories, or even imagine how any being possibly could... Determinism is the predicting category of the three, and that pretty much kills the idea of free will (for obvious reasons).

But free will doesn't necessarily have to exist within the 'three known causal categories'. Maybe it can exist in a completely different causal category, outside of cause/effect/probability/random 'space'. If so, then unfortunately we can never understand it (and it's very mystical). Yet it may not have to exist within those categories. If so, God could know something without forcing it to happen.
