Honestly? This doesn't necessarily sound like a bad thing. Hasbro has been fucking up DND left and right because they simply don't understand it. At the same time, it's a valuable IP with quite a bit of potential in the right hands, and they haven't killed is through mismanagement yet or even close to. If they sell it for a fair value to someone who won't fuck it up, and use that money to specialize in some things they know what to do with, then it could be win-win for the business guys and for the players.
(Of course the question of what they could specialize in that they do know how to make money with is a whole different elephant in the room.)
(Edit: And yes, the chance that Tencent will find a way to ruin it in the name of microtransactions income, and just do a more competent job with that than Hasbro has, is a pretty good one.)
