I think I have to go with Ubisoft. Just old school mix of passionate devs, tears, triple A games and surprises, nice. Sony had the better games but presentation of the show wasn't as good. I dislike their new formula.
Nintendo had fun looking filler games in Yoshi but the show was lacking content (not surprising, it only ran for 25 minutes), Xenoblade 2 doesnt look good, not interested in Kirby, and only a tiny teaser of Metroid Prime 4.
