Well, the first year of the Switch proved to be a lot better than both I and many others expected. The reveal really didn't sell me on the idea at all. I personally find the joy-con's and the handheld mode to be atrocious, but many seem to disagree. Then again; I never liked handhelds and didn't buy it for anything other playing in the dock on the TV.
It has surpassed my expectations by a big margin in its first 10 months or so, let's see what the future holds, longevity seems to be the greatest hurdle for Nintendo home consoles to overcome since the SNES days. With the 3DS probably being fazed out very soon and hopefully some good software and more actual functionality, it should sell well for another couple of years at least, it really puts things into perspective that it manages to probably outsell its predecessor in about one year on the market...
