It could be a first Cylon war movie. Or maybe it's a remake but in the sense of "all this has happened before" and it's the next cycle, or something. Or maybe he just means it will be very different from both series so as to not step on any toes, but just it's own thing.
My God that was exactly my intepretation as well, right down to 'the next cycle' in the neverending story. In fact I wondered once whether or not TOS BSG could have been just that.
