Seeing 3DS support is both surprising, given how long the console is the market and how Nintendo barely supports consoles in their final days, and also expected.
The game we are going to see were based on decisions made 1 to 2 years ago, depending on how long development takes on 3DS.
A year ago (or more), now one really know how successful was going to be and betting everything on the console would be a risk to great to take. Imagine killing 3DS so that the Switch could thrive and then see lukewarm reception to Switch... it would be a disaster.
My take is that this is probably the last wave of meaningful support from both Nintendo and 3rd parties and next E3 will show how the transition from 3DS to Switch has started full force (in 2017).
I really hope they can announce GC, Saturn and Dreamcast games to Switch VC. I don't really expect it as what Nintendo has indicated about the upcoming online plans show otherwise, but it would be really awesome!
Also, i'm torn between a DE and a live press conference. Hope they can actually do both! :)
