There is no such thing as an evolutionary peak. Evolution has no end. Evolution is not a process that has an end goal of perfection. There are a great many changes that could happen to us and will happen to us, unless we go extinct.
You have to remember we did not come about in heavily polluted concrete jungles. The fact that we now do is the most likely cause of future human evolution if we for 1000's of more years continue to live in these places.
I think humans will eventually modify themselves. We're already fairly close to having enough knowledge to do so. Technological changes (e.g. cybernetics, internal nanomachines, etc) wouldn`t be inheritable but biological modifications could be.
Incidentally, the Minotaur was part bull, not part horse, and was bipedal. You`re probably thinking of centaurs.

Even considering anything that could be added that would improve upon our current design, there would be no natural predator(s) to continue the trait along down the line. As I stated already we could only adapt to a climate change, even then we would adapt(most likely) technologically, not through natural selection. Any threat greater than us (aliens, zombies, stuff like that) would not force us into an evolutionary change, but only, again, technologically advance ourselves as a species. Even then, I personally believe, we won't be able to as we as a planet/species find too many differences among ourselves to pull together to face the threat.

The second being we will not evolve again, unless we experience a ice age or some natural event, as we are most likely (for life on earth at least) have reached an evolutionary peak. Meaning that (think about this next part) we as we are (ten fingers, ten toes, bipedal, eyes on top) can not be improved upon (evolutionary wise of course). Even then if you were to add something to us, there would obviously be major drawbacks (compared of course, to what we know/experience right now). The Minotaur (half horse half man I believe) for example seems ideal. This has worse drawbacks than we experience daily. The Minotaur, due to it's size, must either run from a threat, or fight, as hiding (easy for us now as bipedals) would be incredibly difficult.
