I understand that with an international connection it's tough to take chances and wait, but I bet that's not the last change taking place with flight times this far out. I can easily see your original flight going back to its original time or something close to it and you'll be stuck with the 7:30 AM departure and a long connection. It's happened to me with flights moving up in time with AS, I change to the late flight as the only feasible option and then a couple of months later my original departure comes back and I'm stuck with the late flight, paying the fare difference or waiting for an SDC and praying I don't get stuck in a middle seat...
