Much to fans' disappointment, Final Fantasy XV producer Shinji Hashimoto has announced that they have some new information regarding Final Fantasy XV's development, but they are waiting to release it.
In a recent interview with Famitsu, Hashimoto said that they are waiting for the right moment more or less. When this moment will come is up in the air and at this point we might not get anything new until this year's E3.
Hopefully, Square Enix will make liars out of us and we'll get some information before then. Only time will tell.
