Well, I don't think they gave up, as much as just never started with the Wii U. There where only maybe 1-2 titles they wanted to do, and Fatal Frame was one I believe. It was a no go, and since the system is all but over, I guess the effort for Wii U titles was a lost cause.
Here's the article where they discuss dropping the 3DS in favor of the NS, but nothing is concrete yet, so don't get to excited.

I'm thinking the same thing. Unless "N" just does some off the wall shortage scheme, which I've never believed they have done on purpose, I'm thinking the NS should be available rather soon in regards to inventory as well. It's March after all, and not the holidays, and given the best game available can be bought and played elsewhere, there is no "must have" reason to get the NS, except for the early adopters.
BB used to have an excellent exchange repair program years ago, but it ended, and I don't think it ever came back. They used to offer it, and it covered everything, and the sales people would even say if a new model comes out, you could exchange it for the new one. If you brought it in, they would take it no matter what.
I had their warranty for my OG 360, and once the slim arrived, my warranty was due to expire, so I was able to exchange my 360, no questions asked for the slim. Around that time, or a little before maybe, they changed the plan, and I don't know what it covers exactly, but you have to bring it in and have it mailed someplace to confirm the problems, and I don't believe they exchange for products anymore, they will just repair your system. It may take weeks, or months.
I'm sure there is some info online in regards to their warranty service, but it's not like it was years ago, and it changed for the worse.
