He's young, and at the top of the acting list in hollywood. Acting is his life. It's in his blood and the only thing he knows how to do. So if he does retire. HE will be back. I highly doubt hearing keanu reeves saying he is going to retire. I wouldnt duubt him saying he will be taking a break from the life, but to out and out say "im never doing a film again" is just not believable. Not by someone who is so young and Popular. So if he does say he will be retiring you can bet he'll return one day. Especially being a sought after actor by studio's and directors. The right director or studio would convince him to do another film, which will convince himself to do more. This is if he retires. Trust me no one at this age of popularity and extreme wealth ever just retires and never returns
