Making Episode VII visually fit in with what has gone before isn't a problem. Not when you can just change what has gone before to fit with what you are doing now (Episode VII)! I look forward to finally picking up the OT on Blu-Ray in the future, only because all the lens flares they will have to add to match Episode VII will obscure all the other "creative decisions" aka visual faults the 2004/2011 transfers have!

For the record I very much enjoyed the 2009 Star Trek film when I wasn't being distracted by all the blinding lens flares!
