Any plans for a better AA solution?

To me, this was Horizon 3 biggest flaw - the MSAA options available are far from effective and playing at 3840x2160 with 4xMSAA, aliasing is still clearly visible on cars, power lines, shadows, etc.

Are there any plans of implementing TAA to the Forza Engine? Would it be a possibility in Horizon 4? I know that TAA has its drawbacks (like ghosting), but other racing games are already using the technique to achieve outstanding image quality with far less GPU cost.

Hope any devs could comment on this. Thanks!
