Went ahead and pre-ordered the SE finally since it was still up. I hope to get the ME at some point anyway, but at least this way I'm assured the three things I want the most (the case, the coin, and the soundtrack). I also actually quite like the box better, oddly enough.
And since we're talking about Wii U version vs. Switch version: I actually plan to buy the Wii U version too. It's the version I want the most simply because I already have a Wii U, technicalities don't matter to me, and it will afford me the extra laziness of not having to get up in order to continue off tv gameplay. Say what you will about the console, that has been one of my favorite parts of it's design: being able to play right up until the minute a show is coming on tv, pausing, changing the video output/channel with the game pad, and resuming the game during the commercials.
