As a frequent late adopter myself, may I congratulate you on your purchase?The way I look at it, we actually have the advantage of a huge library of titles to choose from once we finally get a platform.
I, too, bought the PS3 for its exclusives, my primary console being my 360. The Little Big Planet games are amazing, I love how people can create and publish levels for anyone to play. I wish I had the creative spark to make my own, however, it's just as much fun to check out other peoples' levels. If you like Zelda, 3D Dot Game Heroes is a lot of fun. Check out Journey and Flower from thatgamecompany (fLow is interesting, but not in the same league as the other two). If you like rpgs, Ni No Kuni is beautiful, and I like the story. Tales of Graces f is also good. And there are the Ratchet & Clank Future games, if you like platforming and blowing things up in creative ways. Have fun!
