Madman Entertainment only seems to make announcements via conventions lately, with even their newsletter offering little licensing news. The last batch of Japanese Transformers series would be perfect example, where Seibertron.com offered the first news. While other cartoon series for children usually aren't announced at all.
Anyway I just hope Madman Entertainment makes sure to get widescreen masters. We definitely don't won't more cropped DVD releases, like many of their Cartoon Network series.
