The official Matrix site was updated on July 19th with "an online conversation between Larry Wachowski and Ken Wilber!" and some information about the commentary.
Weird, when I look at the ComicCon main page on saturday they say WB was going to announce the box set. I really don't see how Star Wars has anything to do with this.
Empire magazine (UK) has an article on the proposed R2 boxset and lists the disc contents as per the first post in this thread, however, they claim that it will not include an extended version of Reloaded.
There's no way this is coming out in October, the announcement should have been in the last couple of weeks for that to happen. As for the extended cut of Reloaded it probably isn't considered an extended cut per se but you'll be able to access the video game cinemas through the White Rabbit function. That was reported months ago.
