Well despite the dozens of heroes who appear in Unlimited, and the logo, the designs for the core 7 characters at the bottom there are all JL-proper designs. Classic Hawkgirl, GL with hair. Hopefully this means it'll have both.
I hope that's the case, as it would be silly to not include the first two seasons of the show. Granted, the first season was light on character development and solid storytelling, but there were some solid episodes in that first season. Season 2's Comfort & Joy is a personal favourite of the series.
