Yeah... I have to agree with Shimarr. Considering the Developers will absolutely not leak any information out, besides what has been reported from the Battle System information releases here in Gaia, there is no other fact(s). And the game could very well be out this October. But that would mean that the game would have serious defaults, and like you said, those monthly updates and such. I doubt Gaia wants to do that, and many people would be upset. Who knows how long those monthly updates could be. Maybe they would be two weeks long.
Really though, next time, don't put this type of stuff in this forum. That is, unless of course, you have undeniable proof of what has been said wherever you found that information, from the developers.
