I think they would of announced it by now if the full game was to be released on the next gen personally. Oh and whoever is getting their rocks off one starring everyone on here really needs to get a life lol.
Think it is why they consider gta online different than gta5. Think they will do a gta online by itself on xbox one with more players per session and such. Will promise more dramatic missions and play, but will be a big glitchy mess.
I like gta online, even with its missed deadlines, broken glitchiness, and underachieving, but when I get an xbox one, I will have moved on to other games and not come back for a slightly prettier gta online.
