Good question. I would assume bugs would still be corrected but I don't think they would want to compete with themselves by bettering the code on the Helix.
I have had them all since 2010...Kemper, ax8, Helix lt, Helix Floor, qc, Kemper stage, fm3, fm9....currently sitting with an axe3 but as long as everyone keeps throwing new code/products out there, I'm always willing to try.
Kempers new code has my attention as does the stadium. If ik throw out an all-in-one modeler , I'd be into trying that too. I like the Tonex feel.
