My local comic shop got a shipment of new games recently. I've been researching some of these, and was planning to buy 'em online, but this works just as well. I bought:
Letter Head It's a deck of playing cards, where each card features a letter and a corresponding point value. Like Scrabble pieces, only better thought out. With these cards comes a book, containing rules for 15 different word games. Most of them are 2-8 players, but they've got a few solitaire variations, which are useful if your friends can't spell.
Proton A two-player strategy game with the mechanism of a sliding-block puzzle. Fits in your pocket. What's not to love?
Q-Turn Another one of those "just when you thought you've won, the rules change" games I love so much. 2-4 players.
Twitch Looks fairly mindless, but fun. Here's hoping. (It was cheap)
