HD vs. Blue Ray

[Lynda Sappington]

WB has announced that starting in mid-2008, it will go to strictly  
Blue Ray for its HD releases.  So what does that mean for the OOtP DVDs 
in the future?  IIRC, I read some reviews that showed the "pop-ups" of 
the actors during the movies - something I was greatly looking forward 
to, since Dan said he worked hard on his part of this and it showed how 
serious he was about acting - were only included on the HD version, not 
the Blue Ray version.  Or did I misread that?  Are the two HD versions 
the same?  I don't have a HD player yet (hubby won't buy one until the 
dispute is settled and the prices go down), but I would REALLY like to 
see the pop-ups Dan talked about!!  Argh.  Anyone know anything about 
this???  Thanks!
