360 getting a blue ray drive?

Could the 360 be getting a blue ray drive? well it seems that there are reports out saying that the 360 may see a external blue ray drive. However, as for now the 360 is sitting back and watching ps3 and seeing if any further developments in demand for blue ray/ consols develop. Hd right now is the perferred format for the xbox 360. I guess it was said that the console would never build the blue ray drive into the console because it would limit consumer options after a purchase of a 360. The use of external devices gives more flexibility to their product.
