OK guys I don't believe these are the same edits (I'm talking about the original trilogy) which were used for the 2004 DVDs.

A new czech dub was created for these BluRay release, because "it contains NEW scenes". The last czech dub was created for the 1997 SE and the only "new" scenes which I remember from the 2004 DVDs were the new Emperor from TESB and the short "We'sa free" from ROTJ. So either these 2 short scenes were a reason why a new dub of the complete trilogy was created, or these movies will include new scenes (again). And there is the old rumour about the digital Yoda in TPM ...

But definitely, we will be SURE which cuts are on the discs VERY soon :-)
