I wouldn't be surprised if they did tie in novels, if they did more comics in the era. We have gotten a Knights Errant, and now a Dawn of the Jedi novel, so they appear to be doing comic/novel tie ins as a regular(ish?) thing now.
The tie-ins to the Legacy era have already started in the novels. Check out Paul S. Kemp's Jaden Korr duology and both Legacy of the Force and Fate of the Jedi series and you'll see some clear, and not so clear ties to the Legacy comics. I can only imagine that as the novels progress that we'll get even more references.
