I really hope that this isn't an indication of the new sound mix. Talk about a noticeable jump in audio sources for the dialogue. Just check out the the line straight after:

Luke "we've got to do something"
Han "what are you talking about

then just hear how different the next line sounds .I don't remember it being this noticeable before

Plus, if these are supposed to be taken from the blu-ray then what colour timing changes have they done, because they are identical to the 2004 versions?
