I've been doing some work on Nike and a big thing with them is the Nike+ membership at 100m people and how they can make decisions on what to make and how to serve it to each customer. I used to think that was ludicrous. But based on what CA was able to do with 50m, I think you can achieve just about whatever you want with the right people working the data - its a plenty big sample size.
