There is little in the way of information or hard dates at this point, but it sounds like there will be multiple Star Wars tables joining the Zen Pinball roster.
We are huge fans of Zen Pinball here at Digitally Downloaded (Matt just reviewed the Wii U version here if you are interested), and I am personally a huge fan of Star Wars. Much like the Marvel tables that came to Zen Pinball, these are tables I will be looking forward to.
Apparently the information popped up on the Sony Blog very briefly before being taken down. Like other Zen Pinball 2 tables purchased on either the PlayStation 3 or Vita, you can get it for the other system for free as part of their cross-content program. No mention at this point if it will be coming to other systems yet or not.
** Update:
More information has come out on this:
There will be 10 tables total, and this month they will include a three pack for The Empire Strikes Back, Boba Fett and Star Wars: The Clone Wars
Additionally, it appears that this will be DLC for mobile, Xbox Live, Windows 8, PlayStation 3 and the Vita. No mention at this time of the Wii U or 3DS.
