I'm hoping its just a rumor or a typo. Also, about the "crossovers" like "No Cloud, No Squall shall hinder us" or whatever, I wouldn't call that a crossover, I'd just call that an easteregg, or a reference. More like a fun little tidbit or inside-joke type thing that the creators put into the game to make the audience go "hey, thats familiar! Wow!" There never was an actual crossover between characters and worlds, where each character and world kept their actual personality and backstory. The closest comes to Tactics with the whole Cloud thing, but even then, they don't combine the two storys so it doesn't really necessarily count.
