Hasbro's Celebrate the Saga collection includes 8 packs.  4 are main line, 2 are for Amazon exclusives, and 2 are Best Buy exclusives.  The pitch I heard was each set has 5-jointed figures and is the last hurrah for the format - at least for now - with 4-5 figures brought back and 0-1 redeco droids.  It looks like they may have enhanced face paint, but it's hard to tell from the photos and I did not hear about it previously.  Each set is due this fall for about $29.99.  Click here to order at affiliate/advertiser Amazon, or click here to order at Entertainment Earth.    Hasbro's marketing copy says:
