There are some lively threads here that are focused on speculating about investigators in future releases. At this point, though, the card pool is so substantial that I can't see getting caught up with playing all the existing 'gators, as fast as we get new ones! Right now I'm getting ready for my first play with Diana, in a build designed for two-player on a team with William Yorick. So she's emphasizing cluevering with some adequate monster-handling. I'm psyched about it and interested for tips about how to play to her basic ability strengths.
Preston hasn't appealed to me much, but I just played Valentino in The Circle Undone prologue, so I got a taste of the resource-focused play style, and I have to admit it's fun. Still, he'll have to wait his turn behind my first tries with Lola (Seeker/Guardian/Mystic), Ursula (aimed at untranslated/unidentified asset upgrading), and Mateo.
What existing investigators are you most interested to try out?
