What Will Mario Kart 8's Final Retro Track Be!? <(^_^<)

[Metroid33slayer]

The final track will be from mariokart 7 because the previous MK has always had 4 tracks included in the next MK. So i'm going to predict koopa city ( known as neon bowser in NA ). It would look great being the only track to have rainy weather effects.
