Only if it's something that interests me. I don't get excited about something just because it's new. But something that interests me, like a new Pokemon game, and I'm all hyper! I hope I'll never lose the feeling of excitement.
For instance I've never *not* been interested in volcanoes, but the recent eruption in Eyjafjallajøkull has increased my interest, and with my bd coming up, there now are some books about volcanoes on my wish list. 4 or 5 actually. + a DVD. And when I smelled the volcano some weeks ago, I went into ADHD mode!
Same for Pokemon games, some series, books, movies, music....
Maybe some would find it childish, but I'd hate to not feel the delicious feeling of excitement.
