My local supermarkets stopped selling Wii U around the time if not a little before ps4 and XONE came out. They do have a 3DS section though and maybe the odd Wii U game. It's all about numbers in the end, if the software is not shifting, it makes more sense to make better use of space.
This is not a big deal for me, as I always buy electrical stuff online anyway.
Nintendo dropped the ball in regards to software and marketing in my opinion, more so the former. If they could churn out those AAA first party games of theirs faster, the system would sell better and then other publishers may publish their games as there is a big enough install base etc.
They also have not made a game that really makes good use of the 2nd display in hand. Only game I enjoyed that made semi good use of it was Zombi U. As much as I love the controller, I hope they don't bother with it for their next system, as it is pointless unless they are going to actually make good use of it. The extra cost could have went on making a stronger system or making the console cheaper.
For example the main game I am currently waiting for is Zelda which is like a year away. I know it will be worth the wait, but still, it should not take them 3 years after system launch to release it.
I not sure how much Super Smash Bros will entertain me, but I am loving Mario Kart 8 and looking forward to the DLC which should be out shortly
