Cameras are almost as bad as laptops - essentially as soon as you pull one out of the box it is outdated - but that's far from saying an older camera should be replaced. If you like the images you are capturing then stick with what you know until it completely wears out or you drop it over a cliff. If you decide to buy, others are right - pixel count is just a marketing tool these days. I would ignore those numbers, I'd even argue that in the type of camera you are looking at ISO numbers are meaningless. I am a fan of the Panasonic Lumix line; but if I were you I'd find a store that rents/loans cameras to poential buyers and take a few to the park to test. Try them in lots of different light and see which one produces images you are happy with straight out of the camera.
