As a serious hunter, the three things I really need in a knife are
1) good edge retention
2) light weight
3) highly visible
1) goes without saying, probably. Field dressing an animal with cold hands and a dull knife is a great way to get a serious cut. S30V in a hunting knife is a great idea- but I would much prefer a more straight edge than the very deep belly of this design, and I think 4 1/2" is too long for a hunting blade (3.5" is more than enough), but that's just me.
2) I have enough heavy things I need to carry- and sturdy knife doesn't need to be heavy. Making the knife a bit smaller would make it more attractive to me.
3) Most "hunting knives" come in camoflage, which is ridiculous (in a practical sense). If you drop it, it becomes a major PITA to find. I want a hunting knife to be blaze orange, or better yet very highly reflective (like a glow-tack or street sign) so when I set it down to reposition a deer, I can find it again without fumbling. It is very rare to wear a hunting knife outside of your clothing, there is just no reason to not have a brightly colored knife. In this regard, I love the orange/camo look. Very practical.
When you are field dressing a deer two miles back in the woods, in the dark, in the rain- you really come to appreciate a good blade. I have never found what I consider to be a great hunting knife- but I think this knife would be pretty close...
