    Bruce, Has this problem come back for you?  I zapped my PRAM and reset my SMC and I still have the issue!  I did however notice that it doesn't happen when my external is plugged in for some reason.  I can't believe that you and I are the only two complaining about this.

    Try putting your Mac to sleep manually, do you notice a few minutes where the screen is dark, but the cursor can be moved?  This is because your mac is writing the contents of the ram to the hard drive in case it needs to hibernate.  The default setting is for the MBP to hibernate after a certain amount of time.  The white screen on startup with the progress bar occurs after your mac has hibernated, so the ram has to be reloaded off the hard drive.  I'm not sure why your mac doesn't hibernate when not plugged in.  I notice that mine won't hibernate if I have an external USB drive plugged in over night and the laptop is plugged in as well.

     

    I'm also not sure why apple made the screen look like it was erroneous, but my sister's new MBP exhibits the same behavior as well.  I'm very surprised we haven't have more people commenting on this.

    I'm not sure why the white screen is the way it is, but after waiting about 30 or 40 seconds the cursor will come back and eventually full control will be restored, at least on mine and my sister's.
