I know I'll probably get flammed for this, but to be honest - the FZ200 seems to have a lot of bells and whistles that you won't need I guess. I'd save a bit of cash and just get the FZ72.
FZ72 offers a range from 20mm-1200mm, so if you're concerned about zoom it's range is more. As for the most gimmicky features they both have panorama, built-in HDR, 3D, RAW (GOOOOOD), and neither have GPS. Both have 23 focus points, but the FZ72 doesn't have an external flash - it's built it only.
That's just me though. I'm sure other people would tell me to shut up and go for the FZ200
