The game is called In Memoriam in Europe, and it’s already released. Not sure if it’s yet released in the US yet, but it’ll be called MISSING: Since January. And it’s one of the best, most original adventure games I’ve ever played.
Basically, you’re investigating two missing persons, and you have to solve a series of puzzles to find out what happened to them. Some of the clues involve searching on the Internet, others require a bit of hand-eye coordination. You’ll get emails that provide hints and additional clues. It reminds me a little of that failed EA game, Majestic. You have to be hooked up to the Internet while you play, because emails come as you complete certain objectives. Anyway, if you really like puzzle-style adventure games, this one’s awesome.
