Blockbuster RAW Announcement, What Will Open RAW?

Jim Ross posted the following at JRsBarBQ.com this afternoon: As best I know, it looks like the IC Title Bout Monday will kick off the 3 hour Raw, one hour early at 8/7 central. Also from what I hear some sort of "blockbuster" announcement will also be made tonight. I have talked to no one who knows the specifics of this announcement but, without sounding hyperbole, it will apparently be significant. SD will also feature the Triple Threat Bout for the World Title that will air live sometime later in the show.

With news breaking last week that next week's RAW will be commercial-free, it's possible this will be the "blockbuster" announcement.
