Yes - about two or three new Cha-based encounter/daily powers per level of powers, of which perhaps 1/4 have Fey Pact boosts. I've been through there hunting for Cha-based star warlock stuff for the last week, so I know she'll find some good stuff there. No new at-wills except the one (Con-based anyway) for the new Vestige path, though.
Also some nifty feats she might like, and separately the familiars (which are based on feats) are pretty darn awesome. I really like how they've done them, and I'd bet your wife will too.
