Well in The Essential Book of K9 a few pages before the comic story appears, there is are articles called:
 * Future Adventures
 * K9 cross section cutways future
 * K9 Future Data output

In these articles they call this K9 "Future K9" but I don't know if they consider it as an new name or if it's just short for K9 in the future. Furthermore the name is not mentioned in a story but just in an article about how K9 will look like in the future.

In the story K9 has memories of his time as K9 Mark 2 and K9 Mark I. So as I have already said it's clear that he is K9 Mark 2 or one of his regenerations.
