99% sure it's a new game. If they announced the game like this, and then revealed it's a port, people would riot.
Evidence this will be a new game.
1. They haven't found out a name (If it was a port, it'd be pretty easy to call it Super Smash Bros for Switch or Deluxe)
2. Vague trailer
3. BOTW Link (Would be unnecessary work for a port)
4. Smash website was completely updated (If it was a port, they'd just add the trailer, since it'd pretty much be the same game)
5. 2018 isn't too soon, Smash 4 took 2 years being developed on 2 systems, this could've been in the works since early 2016)
