Possibly some more info for you guys wondering about how the Best Buy "Smash-Fest" may work -
Last year they held a similar event, where you could try 4 games before they came out (Mario 3D World, Zelda WW HD, Mario Kart 8, and DK Tropical Freeze). There was only one Best Buy set up, and only one unit (the stores display unit) set up for these demos. The reason for this is because these will be run by the local Nintendo reps across the country (these are the guys who go around to all the retail stores and fix the demo kiosks and put up the promo signs and stuff). We only have one in all of Utah. I know him, and he's a cool guy.
So expect it to be similar this year. One location (last year it was at 35 E 11400 S, Sandy, UT 84070), one Wii U set up, and a ton of people showing up to play. They'll want these to go fast so my guess is it will be 2 minute timed, 4 player free for all matches. Maybe they will let you play doubles or adjust the rules slightly, but we'll see. They also had this on two different days last year, so if you can't make it one day, then go the next day. Also, go early. There was a sign up sheet for people to get their name on and Brad would call out people on the list in the order he took names. Don't come on time, because you'll be at the bottom of the list, and don't come late, because you probably won't get to play.
I like what some of you said - At least it is something. We could just have to wait until "Winter" but they are giving us something which is great. Let me know if you have any questions about how it was handled last year.
