Hasbro owns the assets.
Anyway, why would they want to reuse old assets? They can just create new assets with the same iconic features from scratch.
(BTW, the assets for Baldur's Gate 1 were lost, which why Baldur's Gate EE was made instead of Baldur's Gate HD. Damn shame.)
Well, the 3D models were lost so they couldn't re-render them at higher fidelity. Clearly the artwork and sound effects in general weren't, though.
I agree that they could just emulate the old style with new assets.
