According to Wikipedia, it looks like the JLU epsiodes are being released, in order, on DVD. While one is most overjoyed, one continues to wish that they would show similar wisdom for releasing the original series. Not that I'm not glad to get what I can. I'm just saying that since I'm an incurrable completist packrat, while some is good, more is better.
Must goober about the final episode at some point. Though really, it is more of a Batman Beyond episode than a JLU one.
