Witcher 3 developers just said that while the game received some graphical downgrades on PC version, the game only have that magnitude because of the consoles versions. They had more money to make the game bigger, but the downside was they couldn't just optimize the graphics so they could please PC players.
I would have rather had a scaled-down version with a proper PC GUI, cutting edge graphics and PC-centric game design. There's a feel of consolitis that permeates TW3 and turns me off, even more so than TW2. But maybe that's just me.
Still, when it comes to Divinity: OS, I think there's some value in having controller options and split-screen mode. Especially since it isn't going to inflict consolitis on the original game design. Whether that happens in the sequels/spinoffs on the same engine remains to be seen (perhaps based on how much of that sweet console $$$ flows in)
