   London's O2 Arena will play host to an Empire Presents Big Screen event  from August 12 to 14, 2011.  Here is a description of the event from the  
O2 arena website:
"BIG SCREEN brings Hollywood to London at The O2 from 12-14 August 2011.

So how does this tie in to 
Star Wars on Blu-Ray?  Industrial Light & Magic is scheduled  to host a presentation on Friday, August 12 that will feature Anthony  Daniels, ILM digital artist John Goodson, and ILM visual effects  supervisor Bill George.  Besides behind-the-scenes anecdotes, fans can  anticipate there to be some newly released footage from the 
Star Wars saga on Blu-Ray.  We'll be sure to keep you posted as details emerge from the event.

In additional 
SW on BD news, our friend Kenny K. got the following information from a Lucasfilm e-mail:
"Industrial  Light and Magic did go in and make many technicalimprovements, most  notably color matching on select lightsabers shots."
I don't  necessarily think this is shocking news, but it comes as a bit of a  confirmation as to what a lot of fans were expecting.  
Star Wars is forever being tinkered with...or shall we say perfected.  I'm sure it will all look and sound fantastic!
