Any news about VSig support for the new H9000? Or maybe some other platform where we can build or modify presets?

Of course you can use Emote (or the front panel) to modify settings of any algorithm on the H9K as well as change the routing/patching between algorithms.  And you can save Presets of settings within each algorithm.  All of this can be accomplished in Emote, which serves as a librarian and editor. 

But since you mentioned VSIG I suspect you may be interesting in the deeper editing capabilities that VSIG affords.
