I'm in a similar boat to Skyblade, but I don't actively hate Shulk. The thing that annoys me is how almost everyone seems to think that Shulk is almost guaranteed (REGARDLESS of leaks) and blows off Isaac's chances whatsoever. That's what makes me irritated about Shulk. Isaac and Shulk are literally in almost the exact same circumstances. Well, I should say, Shulk is literally in almost the exact same circumstance now that Isaac was during Brawl, in that he's got one fairly popular game behind him, but that's really about it.
Isaac, however, had two games, both of which sold better than Xenoblade. I don't have any problems with Shulk getting in... its the whole idea of Shulk getting in over Isaac that unnerves me, as well as the attitude I've seen thrown around regarding Shulk by most people.
Best-case scenario is that both Isaac and Shulk are announced in the same trailer. That's what I really want to see, even though I doubt its going to happen.
