Smash aside because it's too early for me to even begin to talk about it, especially since I'm not a huge Smash fan--
Honestly I'm a little disappointed in the 3DS announcements purely on the notion that I want most of them on my Switch. Why in God's name would they not put something as iconic, masterful, and highly demanded as Luigi's Mansion on the Switch is beyond me and does nothing but frustrate me to no end. I want to be done with my 3DS just like Nintendo seemed to advertise when first pitching the Switch as this crazy all encompassing hand held AND home console, but when they announce stuff like this, I find even less reasons to want to play my Switch. Now, if this also means the Switch won't be getting Virtual Console for NGC because of things like this, or only select minute titles that get turned into ports or HD remakes, I'll be even more frustrated.
Oh hey, Smash, that's cool too, I guess. (Sorry I'm a pessimist with this stuff!)
