Shin'en just shot themselves in the foot.
I don't know how much the rest of you know about dynamic shadows in futuristic racing games (I'm an expert), but honor and shame are huge parts of it. It's not like it is in Super Mario 64 where you can become successful by putting a circular dot under the controllable object. If you screw up dynamic shadow casting in futuristic racing games, you bring shame to yourself, and the only way to get rid of that shame is upgrading your lighting engine to PS4 standards.
What this means is the futuristic racing game community, after hearing about this, is not going to want to purchase FAST Racing Neo for the Wii U, nor will they purchase any of Shin'en's games. This is HUGE. You can laugh all you want, but Shin'en has alienated an entire niche racing genre with this move.
Shin'en, make the sun in FAST Neo Racing your only real time shadow casting light source or you can kiss your business goodbye.
