I know the DCSH was in the July or August issue of Previews.
I believe you're right. Thank for correcting me. A LCS stocked JLU singles (Luthor/Shining Knight wave) around the same time as they started to appear at mass retail. But DCSH figures showed up (or became available) much later after they showed up at mass retail (3-5 months). But 2007 is a poor year if you're trying to find a consistent pattern for MILLIONS of reasons that have been covered in hundreds of other threads. Hopefully 2008 will be a banner year for Mattel Action Play and fans.
