Nope, we are not getting Kratos. We are talking about the rumor that a title "God of War" (戦神, Ikusagami) might exist in Taiko no Tatsujin Kimidori, possibly added just last update. It was not clear how to exactly obtain it as of now though.
The question was also brought to the Taiko Team Twitter last year-end, and Etou was reluctant to answer to just one person instead of officially releasing the info to the public openly.

Currently wikihouse's list of titles puts a placeholder for this under "Sharera Master" (シャレラの達人) and before "He who Hunted the Double Dragon" (双竜を討ちし者, FC Souryuu no Ran Oni). This is recalling of the fact that "God of War" was a runner-up nomination in the livestream vote that "Sharera Master" emerged, for Full Combo-ing Xa Ura Oni.
