The alternative is that they find an 'agreement' and SEGA will release it as a HD remake for all consoles and PC.
Like they did with the Streets of Rage Remake? Oh wait.
Once that came out, they shut it down, wouldn't even let the guy patch it.
They're only letting the Phantasy Star Online private server keep running because PSO is dead in the west, PSO2 ain't coming out here if it's been delayed for over 2 years now and I doubt we'll see Nova either, Sega doesn't care as much about the west anymore, they didn't even put up the money for Bayonetta 2 meaning it became a Wii U exclusive.
