I saw this e-mail from Champion on another forum:
We are coming out with some new ACANA formulas, the first is Duck & Bartlett Pear, it is a single source protein consisting of duck meat, duck fat and duck liver. The protein level is 25%. The other formula is Lamb & Apple which again is a single source protein consisting of lamb and the protein percentage is also 25%.
These new formulas will be available for purchase by the end of November.
