I think there are over 30 figure cards now, 6 or so two packs (big box display things), 1 Jedi Starfighter and two box sets, so quite a bit.
The box set suck, I have one and sort of regret and unless the other turns up for very little won't worry about it it as there is nothing new in it. The figures are great though. They were released in batches of five and a number of exclusives.
