If something has the exclusive ability out of the box to play the new format movie, that would be considered a player. Buying another add-on part for $130+ is not.
So should we count all computers as DVD / CD players because they happen to be able to play CDs and DVDs?
Like I've said many times now, if you count every PS3 sold as a player in the "war", you are going to skew your results a lot. If the PS3 has sold say 6 million units and 50% of those are used as Blu-ray players, your numbers are off by 3 million users.
