Heh, it looks like Ed has done quite a lot of repairs with that book: first Eilistraee is back, now Finder (even if he was already back, since he was included in the PHB appendix. Actually, I don't even recall WotC saying that he was dead, he was just MIA AFAIK).
It would be nice to see some details on how that happened, but I guess that they will come when ready.
