not assigning a score, but:
clear negatives: battery life, paid online
worrying: price, no talk of backwards compatibility, little 1st party stuff for launch considering the WiiU got pretty much nothing the last 2 years and especially no Pokémon announcement (even just a port would've done wonders for the Switch)
positive: Mario and Zelda looked very polished, Xenoblade 2 (might be early in development though), japanese 3rd party support, still a good concept that could spread to casual gamers by word of mouth
