Is there a sequel to the SD49225T-HN that's significantly better?

I love the zoom, picture quality and night vision of the SD49225T-HN, but I'm wondering if any of the successors have better quality? Especially interested in clearer and stronger optical zoom.

Interesting. Are there any tests posted comparing the 25x zoom to the 45x zoom?
