Xenoblade is an easy 10/10 game in my book, but DE being a rerelease will be partially judged based on what it is adding over the original. DE seems like a solid update but I don't think it really brings enough 'wow' factor that people would give it 10s. So I don't really see it hitting 90s metacritic.
So for those like myself who have never played the original, it's going to be something else!
