I just read this somewhere:
from the Hasbro Q and A:
Deathstar Briefing Battle Pack SIX of officers. Vader, Tarkin, Motti, Tagge, Officer Cass, Chief Bast, General Wolf Yaluran. Exclusive to Previews/Diamond Comics.
Republic Commando Squad Battle Pack exclusive to Entertainment Earth, HasbroToyShop and StarWarsShop.com. (Sev, Fixer, Delta 38, and Scorch battle three Geonosians!) Available November 1, 2007.
OMG - I am SO HAPPY - I've been wanting the Deathstar breifing since I saw SW back in '79!!!!!
And the battle squad pack is a very nice addition too!!
