The size of game is unreal i really want a 5 day or so advanced preload seeing how it would take 12 hours to download on day its out.

I believe Bethesda's last few releases had a pre-load option on Steam - I know FONV did, I'm pretty sure Brink and Hunted did too. However If they've said anything about RAGE I'm not aware of it (mod aren't Bethesda employees).
