Pre-planning works for some people some of the time
If your life is such that pre-planning works for you, then great! You can still pre-plan within the structure of GTD, no problem.
What David Allen was getting at though is that, for many people, no amount of pre-planning can predict what the actual priorities are going to be. In my situation I may have a very clear idea of my priorities the evening before and spend time deciding the most important thing to get done tomorrow. But I can guarantee that before nine am, something has happened that affects my priorities (a phone call, an email, a front page news story). At the very least, I will need to reassess what I had planned to work on against all the new work coming in and that is true GTD.
To be able to confidently say "not right now" to the new work or to say to the old work "this new thing is more important than you" is the benefit of having all of your committments out of your head and available for review at any moment.
