Its probably as simple as them Re-opening their Specialist games Department, and proving that they could do Boxed Board-Games again with "Silver Tower."
I feel that, effectively, they'd outsourced the IP and License for Board games in the past because they were not equipped, unable, or didn't want to focus on it themselves.
Now, they can do it themselves , and make more money.
Having two warhammer quest games at the same time might also have something to do with it.
But it still seems kinda odd if you can have another company pay all the production/distribution costs to make games with your IP and you just sit back and get money without having to do anything.
Edit: It's the reason why Disney shut down Infinity, saying they'd rather just farm out their IPs and let other companies make games with their characters.
