Don't expect anything, because Eddie said even he does not know where this thing about pre and post monthly originated from.
They have all the data and they can see what site has contributed the most to their profits and then they reward them. It might be that the .us site had some highroller that gambled a lot and that boosted their profits. (I know .us is a sweepstake site, but they still make money from that)
Let's hope the profits was big enough to reward both sites.
