Spike had 3 making of specials (aired one w/ ea. PT Ep.) 1 - new fighting (with lightsabers) from AOTC (had behind the scenes clips - also behind the scenes footage of Vader with helmet off but in suit dueling with Mark Hamill during rehearsal)
2 - History of Boba Fett (with the footage in Yuma with Fett's helmet off and getting his jet pack on), interviews/footage with all three Fett actors.
and the final one 3) was the making of the Zam Speeder chase
I would imagine there will be something additional thrown in w/ ea. of next weekends OT airings
