Stern's marketing have done something different with this release. They have a KISS Pinball dedicated Facebook page.
https://www.facebook.com/kisspinballMakes sense, as its more likely to attract people who are into KISS but not necessarily Stern or Pinball. Those people are more likely to 'like/follow' a specific Facebook thread that is just about KISS pinball and does not include other pinball stuff that they may not be interested in.
And if it hasn't been confirmed elsewhere yet, this Facebook page confirms that Borg is the designer.
