Actually, it means that there won't be any remakes. Since G4, GameFreak has always made sure that we could connect to the previous generation. Only G1 and G2 are outsiders, until they got remakes made. So unless they break the mold and make G7 incompatible with G6 (which I honestly doubt), then they have no reason to make one.Going by that logic, we wont see RSE remakes til Gen7.
Don't get me wrong. If they were to remake the third gen, I'd buy the games on day one. It's just that there's no real reason to do it other than money, and GF has often stated that money isn't their main priority.
