As is normal with these initial trailers, they're more for hype generation than for clear communication of the additions and changes to the game.
Hopefully the skating changes give players on both sides of the puck more control over their skaters. The current visual control is usable, but still clunky at times. I'm a bit pessimistic that this will end up further encouraging a prima ballerina meta, but I hope it's a more balanced than that.
Any improvements to the AI will be welcome. We'll have to see this in action to make any real judgments though.
I wonder if with the new skating changes players will need to actually open their hips to square up to the pass to do a proper one-timer? That would add a bit more skill than the current method.
