Paper is a case study of console market, where the console makers are identified as group G which shares a distributed knowledge of current consumer expectations. According to the basic logic, it is reasonable to expect that if it is commonly known that a choice A is better than a choice B, any agent i will prefer the choice instead of the inferior one. In case some console makers chose a completely different outcome which is rather based on belief instead of common knowledge.
