Lower specs and the board being older doesn't really matter. It's the games that matter, and Sega's board doesn't really have a lot at the moment compared to its competitors, Taito and Namco.
As of right now, GGXrd is the biggest game announcement that the Ring Edge 2 has in its lineup; otherwise, it only has the likes of UNIB, Phantom Breaker and an upgraded port of GG:AC to its name.
