Dragonfree is correct. The prizes are like tiers that you unlock, not point-buys, and they're cumulative; you get all of them, not just the "best" one you qualify for.
As far as the timeline goes, I'm still working on the next update, which I'll post tomorrow. The reviewing period ends tonight, midnight EST, in about twelve hours. However, because the update won't be posted, if you completed the weekly challenge before midnight Sunday I'll give you until Tuesday, October 2nd to say what exactly what you'd like to do for that, so you'll have a day or so after the update's posted. You can either wait to say what you'll do for the challenge until after the update's been posted, or you can come up with an initial action and then change it before the end of Tuesday if what's in the update makes you want to do something different. I'll then aim to get the last update out on Saturday, which is also the last day for claiming prizes for the game.
