well, here are my guesses, X.XX.TX is X.XX.20X, if the last one is years, and the middle is month, then X.1X.20X, because there is no "0" in alphabet, so, i would say that at november/december the game will be fully announced, also, if the X at the beggining its not the day but the month, is probably a 9, maybe this friday, they will announce it. But, it could also be eternity, the name of project/game, assuming that the . at the beggining is not meaningless and the other ones are not just for separating the numbers
