I think you're probably safe. Keep in mind that Volition left out both the Bloodsucker pack and the Unlockable pack from the SRTT full package based on negative fan feedback. I don't think they would actually force something like that again as part of any package.
You're probably right. And I'm down with throwing some dollars at Voilition for just about anything really...just cause they're a cool dev house. Though to be frank I'm kinda getting a little licking my own ears crazy here trying to avoid all the pre-release lets plays going on, on Youtube.
