Unfortunately the authors were performing a work-for-hire on someone else's intellectual property and as such, Hasbro is entirely within their rights to terminate the agreement at any time. Writers operating work-for-hire have no intellectual right to their work whatsoever. This is what screenwriters do, and what writers of book tie-ins (Star Wars, Battletech, etc) accept as basis. They do it for the money: a sci fi novel will maybe get you a $5k advance if you're famous while the first step of a WGA screenplay gets you $75k. Greg Bear was willing to lock himself away from all his other projects for four years to do the Forerunner Saga for Bungie. Brian Aldiss doesn't do all that shit in the Star Wars universe out of love, he does it out of avarice.
It's a bummer that no one will ever see their shit, and it's more of a bummer that they got ahead of themselves and wrote Book 2 without any serious oversight, but I got about eighteen linear inches of work-for-hire that nobody will ever see and if I ever once decided that I was going to sue for breach of contract no one would ever so much as read my shit ever again.
