Wait until tomorrow to preorder 13 pro?

I'm kicking myself so hard for not preordering it literally yesterday or anytime in the past like 2 months. But I'm sucking it up and getting a spot in line now, even though it costs $900 more for the same specs. I can always cancel later. Anyways, I might be wrong but it seemed like the last October batch sold out in like a day, do I have to worry about the same happening with the November batch? I REALLY don't want to wait till December to get a laptop, but I want to wait until tomorrow to make sure of some financial things. I'm worried though, because last time I said that.... well look what happened. Thoughts?
