Kotaku reports that a number of their readers have received invites to an "exclusive pilot rewards program" for Xbox Live.

Only a "select few" have been chosen for what looks to be a trial run of the Xbox rewards program starting October 21, using a criteria that no one has deciphered yet (for instance, our own Jason Chen has a gamerscore of like a bajillion points and he hasn't received an invite). We're assuming that, like Club Nintendo, Microsoft will cut the exclusivity to their program eventually. Then again, maybe Microsoft wants their rewards to feel like a just-lucky-to-be-there type of deal indefinitely.

I, for one, could care less about free t-shirts or demos. But give me a radioactive-green Mastercard and I'm sold. [Kotaku]
