Koi Turnbull has been mentioned as taking over from Paco Medina as New Warriors artist. No idea for how many issues but I had a quick search for some interior art so we could get an idea of what sort of artist he is. Here is a single page from an old Black Panther of which he did about twelve issues, he's also worked on Fathom, some Aspen stuff and a couple of one off issues for DC.
