I was seriously on the fence about my recent vehicle purchase (2015 Sedona) for this same reason. I've not owned a direct injection engine before so this will be a new experience. I was not aware the oil darkened so quickly, but it makes sense that much like a diesel engine, the soot generated would darken the oil quicker.
I'll definitely keep an eye out for oil consumption. Most port injected engines I've owned have consumed some amount of oil... My Chrysler I add about a quart in a 5k-7k OCI, my Nissan is about a quarter quart low in 10k, and my Odyssey drinks a quart every 3k or so. So it's rather all over the place. I can't imagine the new DI engine being too much worse than what I've experienced in PI engines, but I could be wrong!
