A few opinions on things.
First, I think the chances of a Sony-owned character are a fat 0%. If the characters are just a response to your "dream picks. ", then ok, that's fine. Zeratul is like that for me. He would be so awesome, however I'm never ever counting on it. But even he has showed up on a Nintendo console, which is why I think those seriously wishing for Sony characters as of its a possibility should abandon those wishes as soon as possible. And as much as I want Master Chief, my fellow spartans should let go of that dreamz too.
Second, after Vergeben the Seer's statement this morning, I am also in the Bamco camp or the new company camo. However, I'm am not in the Capcom camp...the Campcom. In fact, I wouldn't even consider going near that camp during the fighter pass. They've got a ton of great characters and worlds, this is true. But I think Sakurai and Co. are trying to give all of their third-party partners more characters. Capcom was one of 2 third-party companies to get new fighters in the base roster. If they have anything coming, I think it's post-pass.
Yhurd (autocorrect didn't correct me, so...), I think Heihachi is going to be a Mii costume; Nightmare would awesome, but I don't see it happening; and KOS-MOS...I mean, maybe? But I think Lloyd is our guy. He's got the most going for him IMO (Sakurai interview comment about him, Mii costume in 4, popular in online polls, Tales Of series represented, unique design). At least for Bamco...
