According to a datamine, Wave 6 should contain one course from Super Mario Kart, two from Double-Dash!!, one from Wii, and four from Tour. This could be inaccurate, and I'll explain why in my prediction, but I'll assume it is for now.

Tour currently only has three original courses that are not in the Booster Course Pass, so it's safe to assume all three of those plus one more that hasn't been released yet are coming in Wave 6.

The only course variation from Super Mario Kart that hasn't appeared as a retro track in any Mario Kart yet (save Super Circuit which had every SMK track) is Vanilla Lake, so while it's far from a sure thing, my money's on one of those. For guessing's sake, I'll say Vanilla Lake 2 since it's a little more complex.

The reason the datamine could be inaccurate is because we weren't supposed to get a Wii course in Wave 5 but we got Moonview Highway (I believe we were supposed to get a second original course in addition to Squeaky Clean Sprint). So the Wii course could be out, but most people seem to believe it will still be in because according to the datamine it's supposed to be the very last course in the entire Booster Pass, making it the final course in this gigantic, decade-long game, and I'll be damned if that was supposed to be Moonview Highway. Nah, anything other than Rainbow Road in that slot would be a massive letdown.

Double-Dash!! is totally up-in-the-air. There are so many courses to choose from. I'm gonna say please no more character circuits or city/traffic levels, as we have a TON of them in this game already. I think we're due for a Bowser's Castle, as there are surprisingly no retro Bowser's Castles in the game yet (usually there are like 5). So the other should be Wario Colosseum, Dino Dino Jungle, or DK Jungle. If Wii Rainbow Road is out, then I could see GCN Rainbow Road being shuffled into that last spot though.
