Typically a complete set is done in about a week. People are more thorough than what I remember the first time I downloaded one of these way back for NCAA 06! People have had the season pass edition since July 6th, so we're more than halfway there I would think. They don't post updates usually. I think we'll see them by the end of the week.
In the mean time, I just play online matches to get the hang of things (after a couple exhibitions against the CPU). Try different teams, maybe do the new Heisman mode, etc. Then start the dynasty when the rosters come out. Trust me, you'll be mad if you start a dynasty without the names. Once they come out you won't be able to stand seeing QB 5 and DT 99 anymore, and you can't add them mid-dynasty. I MAY start a franchise just to see how the new recruiting works, but I'll probably exit without saving.
