Earlier today, an employee from the Wheaton Best Buy posted an ad on Reddit detailing which titles Nintendo is demoing during their Best Buy event this Wednesday and Saturday. From the looks of it, we'll be seeing titles we already know about: Pikmin 3, The Wonderful 101, New Super Luigi U and the remake of The Legend of Zelda: The Wind Waker. Until Nintendo or Best Buy confirms or denies anything, this will remain a rumor.
On top of the leaked list, The Best Buy website has updated the participating locations of the E3 demos, and many have been either removed or relocated. Here's the updated (and much smaller) list:
