With regards to "new" characters, it doesn't even have to be really new ones. All you have to do is remember all the people Mengsk worked with when he was still emperor. If you recall in the SC Evolution book, it was made clear those people are still around. Doesn't take a genius to know they might try overthrowing Valerian so they can have the Dominion for themselves. Thus the whole "new" characters matter isn't them being new at all, just that they were never named in the past.
