I've been adding up all the numbers confirmed for the carded figures including paint variants (Clones, Pit Droids and Imperial Officers in Saga Legends) and we've got the confirmed 60 for the basic line. Then we've got a confirmed 28 for the Saga legends, which is pushed up to 36 with the extra 3 Clone officer variants, 3 extra pit droid variants and 2 extra Imperial officer variants.
I noticed it totalled 96 and it rang a bell in my head, then I remembered 96 is also the number of individual characters released in the vintage line (if you count Yakface and exclude the Droids and Ewoks lines).
Quite interesting. Of course, this could be made moot if Hasbro does any running changes in the main line.
