The Canon PowerShot SX40 HS is probably a better option. I've had no problems submitting with the SX30 and it looks like the new model has an improved sensor. The drawback is the speed of these cameras, I find it much harder to take photos of fast moving subjects. But I wouldn't usually carry an 800mm lens with me and the SX30 is quite sharp at the long extreme. I don't think any of these cameras are sharp through all the zoom range, most of them are poor at the wide end. Mine seems to of developed a fault. I have had it over a year and have definitely abused it but these cameras aren't as tough as the DSLR's that I use.
I'll wait and see what comes out in the next few month, I'd sacrifice a bit of zoom range for a larger sensor with better image quality. I hope Canon or Sony do a bridge camera with their larger P&S sensors.
