Since it won't even be using a 3D engine (let alone any modern APIs like DX 12) I would think that any tweaks needed for WINE to run it well should be pretty minor. Using that same logic though, I would have thought that making a Linux release would have also been pretty trivial for Blizzard to do, but given their history I suspect they have a policy of avoiding this.
