Tom Selleck will make a cameo appearance at some point in the series
To pass the torch, as it were.- Could happen, given how Hawaii Five-0 had its lead interact with a (very creepy-looking) CG recreation of Jack Lord a few years ago. Hopefully they won't have to wait till Tom Selleck is dead, thereby negating the (very creepy-looking) CG recreation aspect. John Hillerman's Higgins, on the other hand...
Katsumoto will ultimately keep his job at HPD
However, he will probably be demoted to patrol and will have to work hard to get his detective's shield back.- He got his job back and kept his rank/position.
