Before someone is going to ask it, and I know there is someone going to, no you simply cannot get any game early through a preload. That's not the way it works. If it is going to leak then through a cardridge Dump.
Every preload is encrypted by a 128 bit digit. This is the cryptoseed. A Bruteforce would take wayyyy longer then until the games actual release. The little update you get for your preload after the games release, is literally just that 128 bit digit, so that the console can decrypt the game.
