Even Bendis (who pushed to get Kon back) confirmed Kon wasn't around anymore because the new Superboy had to get all the spotlight.
Superdad's story arcs and his own character were all focused on the new kid, both in the main SM books or team books. Look at what SM talks about all the time in Hitch's JL. In one issue, he even said he doesn't care about Earth or Krypton, and his family is all his world.
Obviously, the interactions with BM and Damian had to stay for the launch of the Supersons book, lol
