According to http://www.r2-dvd.org/article.jsp?sectionId=3&articleId=4500 the release of BTTF has definitely been put back to December. Their guess is that Universal are trying to get the additional R1 extras onto the R2 release. I have a pre-order for the R4 version from cd-wow (a great price as we all know) but I'm tempted to cancel it and hang on for the R2. I know you should really buy because of the film itself but its always nice to know that you have the best version of a DVD. Decisions Decisions.
