Rumor- Mario Kart 8 Deluxe to feature other battle modes

Nintendo's Poland website seems to have leaked 3 other battle modes coming to Mario Kart 8 Deluxe.

Alongside the already known Balloon Battle and Bomb Omb Blast. We have the return of Coin Runners, Shine Thief/Shine Runners and a never before seen Piranha Planet mode.

So I take it Piranha Plant mode is like the bomb mode except you just solely use piranha plants to smack into each other. Either way I am interested in having the fun hectic battles again.

This is awesome, but I still cannot see myself buying this unless there is an upgrade option at a cheaper price for Wii U and DLC owners. I love that they're adding all this battle mode content but to me it doesn't justify paying another $60 when I already bought the original game and it's DLC, I've already spent over $70 on it.
