Thanks for the link, oldbroad. I got an e-mail regarding this as well, and I voted that I would definitely prefer a hotspot revealer. I don't like pixel hunting, and I can't count how the number of times I've gotten stuck on a puzzle because I failed to find a hotspot/item. I can do without the hint system.
Either way, I'm looking forward to this game. I'm getting some Gabriel Knight feelings based on the plot description and screenshots.
