I think there'll be one next year because there's still room to tinker with the various elements to allow US and its partners to make this worthwhile.

I'm not so sure about a GS in 2013. The bloggers came late to the party this year. They won't be so slow in 2012. Each will probably have some sort of preview article about the promotion next year. And once the bloggers are all over it, I'm sure you'll start seeing articles in the general media about GS. Remember that a number of bloggers also have MSM contacts or occasionally get quoted in articles done by newspaper and magazine writers.

Although the increased numbers brought in through these channels may be good for US's partners in the short term, I think we've seen what happens when the spotlight of publicity hits matters that we normally take for granted (Sharebuilder, mint, certain award redemptions on various airlines).

If this is the way things unfold, I'm somewhat pessimistic that this promo will last beyond another year or two.
