Microsoft: No replenishment projections

In response to Xbox 360 replenishment questions, a Microsoft spokesperson said, "We don't want to get into short term projections right now because any number we provide will become grossly outdated very soon.  Retail replenishment varies market to market and consumers should check back with their retailers frequently."

The spokesperson went on to say that the company is working "around the clock" to get more 360's out week after week.
Is this type of reply meant to leave consumers worried about a shortage, hence encouraging higher demand? Or is it just legitimate inventory problems?
