Lord Charlie chimes in on a keen observation:

Hi there! I don't know if you guys noticed but on the back of the Carded Jango Fett Deluxe Figure and Mace Windu figure, there is a picture of the (spoiler)Deluxe Count Dooku figure that was on the official site a few weeks ago, and it says DARTH TYRANUS instead of COUNT DOOKU. Just thought you guys might wanted to know.

You can compare the dual character names mentioned on the eBay card back listing here and the official site's character mention here. (spoiler ends) Great find Lord Charlie!
