If this happens, this could be the beginning of the end for DC Direct, at least for action figures.
Now that Mattel has the license for the entire DC Universe proper beyond just Batman and Superman with the DCUC line there is little to entice 6" scale figure collectors besides artist/storyline specific versions of the characters.
If HT (or any other 6th scale figure maker) gets the rights to their universe, their will be little point in continuing their DCD line of 13" collector figures since the scale is so close. If DC Direct's BB and TDK figures are any indication, collectors would be better off paying a little more for a licensed interpretation of the comics versions, rather than the ones that are "straight from the source".
Well, at least DCD would still have their statues.
