With respect to the DC Relaunch, I'm a little intrigued by the costume differences between Superboy #1 and what appears to be Superboy in Teen Titans #1.  I also notice that they do not mention Superboy in the solicitation for Teen Titans #1... 
 
" As Red Robin, he's going to have to team up with the mysterious and belligerent powerhouse thief known as Wonder Girl and the hyperactive speedster calling himself Kid Flash to stand any chance at all against a living, breathing weapon with roots in another world! They – along with a few other tortured teen heroes – will be the Teen Titans"  
 

Well from the blurb--"a  living, breathing weapon with roots in another world"-- it sounds like Superboy is the villain of the first arc, so he probably doesn't get a costume until they defeat/save him. And that costume appears to be a black shirt.
