In the pics over at Rebelscum's rumor thread, the vintage carded Super Battle Droid is, of course, close to the same one that's been in Saga Legends for years, no ball jointed ankles. But it has a pistol or something in one hand, which is strange...don't recall them holding anything ever.
Let's see, I could wait and get the carded one with it's pistol for $8+, or get the Arena one with more articulation and another figure now for $13 (I think).
