Believe it or not, it's been six years, almost to the day, since Firaxis very successfully brought back the X-Com sci-fi strategy series with XCOM: Enemy Unknown. In fact, on October 9 it will be six years to the day, and it's possible that the developers might be doing something to celebrate the birthday.
Solomon was the designer on XCOM and XCOM 2, while Garth DeAngelis was the producer on both projects and Greg Foertsch was the art director. In other words, it's the top trio of XCOM execs just shooting the breeze, speculating idly about "doing something special" for the fans.
Could there be more to it than casual chit chat? Six years is an odd sort of anniversary to make a big fuss over, and there's no obvious reason for it that leaps out at me. But it's interesting that games from the original X-Com series were released in 1994, '95, '97, '98, and '99, but not 1996. Coincidence? Hey man, I just work here.
