An interesting little tidbit came across the news wire today...
The Galaxy Bricks website is in the process of building a visual guide to the LEGO Star Wars line, past, present, and future.
The minifigure page appears to be shaping up quite nicely. I didn't count how many figures they've cataloged, to date, but according to LEGO's 2010 annual report there have been 314 Star Wars minifigures since its inception in 1999.
Check out their page when you get a chance.
Best of luck, guys!
