The reason for the reduction was due to many people complaining that the interval was too long in between oil changes.

Where did you hear that? I find it hard to believe that BMW would change a oil change interval based on customer feedback. These intervals are engineering decisions so I suspect that changes in the engine technology or reliability data is likely the reason for a change.
