I'm sure the sprinting will be fixed when the game is close to finished, and I really hope for a realistic implementation of the system. I imagine that when you jog/run, you should be able to move and strafe kinda freely because of the low speeds, just like real life. It's not hard to take a quick step to the left when you're joging at a low pace. When you sprint in real life, you have high momentum forward and you turn by kinda leaning to one side. I hope that when you sprint in game, a mouse movement makes your character lean to that side, and you slowly start to turn. This would make chases through wooded areas really exciting as the player who controls his character the best would make it through the forest the quickest. Same goes for towns I suppose, it should require skill and timing with the jump key to make a quick getaway. When the stamina system comes I hope you need to time your sprinting to get away from zombies. A zombie should be faster than you when you jog/run, not much maybe, but a bit faster. Eventually the zombie would catch you (and hopefully be able to grab you in some way) if you don't turn a corner or a tree and quickly sprint out of sight from it. But you have to careful as you can't sprint forever. The zombies will never be truly dangerous if you can run away from them as easily as you can now. Also, I hope your stamina increases with how well fed you are. This should be a hidden stat, but you should be able to tell that your starving character can't sprint (or even jog?) as long as a healthy character.
