As I write this, auctions for R5-M4 are popping up.   This may well be the first-ever action figure labeled "Star Wars Day: May the 4th Be With You" and is being reportedly sold in Orlando's Disney theme park(s).   I don't have prices, I don't have specifics, I don't know if it's in Anaheim, and I don't have one yet myself.   But I do know you can see one if you click here.

UPDATE: Long-time reader TotallyRawe left a comment indicating this is indeed showing up in Anaheim.  Buy one!  Or two, send me one.  Happy hunting droid junkies!
