Sony Cyber-shot HX100V verdict

Accordimg to them the Sony and the Canon tied for Image Quality 18/20 and the Fuji was 17/20.
Interesting reviews if you want dig back further on each camera.

The Panasonic FZ150 should be in your title--it's the Canon's stiffest competition.
"Compared to the current competition, I'd say the SX40 HS enjoys a very minor edge over the Panasonic FZ150 and Sony HX100V on noise levels, although it's a close thing and they're all fairly equally matched in real-life resolution. That's as far as in-camera JPEGs are concerned. The FZ150 does however enjoy one big advantage over the SX40 HS and most rivals though by also being able to shoot in RAW, which in my tests allowed significant highlight retrieval which was forever lost on JPEGs.

There should be firmware hack out in a few weeks or so that will enable the SX40 to shoot RAW format.

Will it void my warranty?

Q. Does using the CHDK program void your warranty?Edit
A. First, please bear in mind that CHDK comes with no warranty for any use; you use it at your own risk. What follows is just a few thoughts, and is not a legal opinion. Many believe that using the CHDK does not harm your warranty, since it is said to be loaded into the memory only temporarily (turn off the cam and it's gone completely) and that it leaves the original camera firmware untouched.
Canon Tech Support says: "Unfortunately, any upgrades to the software of the camera not performed by an authorized Canon Repair Facility, would void the warranty." ... and ... In further discussion with Canon about this specific hack, their response is: "If it is not Canon firmware the warranty would be void."
Is it an "upgrade" of the camera firmware when the firmware remains untouched? It's up to you to decide. Don't use it if you are not willing to take the slightest chance. Many many people have used CHDK on their cameras (including some very experimental versions) and there is no report of any permanent malfunction. Thus, CHDK appears to be quite safe to use as long as you make sure that it's the CHDK and not a real firmware update (A real firmware update which is not an official Canon update could alter or completely screw up the camera and will void the warranty). Addressing their second comment (i.e. "if it is not Canon firmware"): CHDK is NOT firmware. By very definition, FIRMware is software that remains in the memory of the device when it is not using any power-source.
However, this is not a legal opinion and the user accepts all risk of using it. And as a practical matter, if you send your camera in for warranty service, and Canon says your warranty is void because they found evidence of CHDK on your memory card, there is not much you can really do (what are you going to do? Spend thousands of dollars suing them to get your camera repaired?)
However, you can just wipe or remove the card. 
NOTE Under some circumstances, a memory card is not be needed to determine that CHDK has been run on the camera. The canon firmware writes a log to internal flash when a crash is detected, and this could contain signs of CHDK.

I had looked at the Panasonic to compared it with the highly touted Canon and felt that if I were to buy a camera, the Panasonic with its Leica lens would be my choice (and I've been a Canon fan going way back to my AE-1).
But, as I always say, "that's just my opinion, I could be wrong."

You have to load this every time you turn the camera off?
"(turn off the cam and it's gone completely)"

The way I understand it, this firmware is loaded on to a memory card, and when the camera boots up, it loads the firmware on the memory card. When another memory card without the firmware hack is installed, the camera boots up with it's original firmware. This is a good thing.

Well that's not too bad. I thought if it had to be loaded onto the camera each time it's turned off it wouldn't be worth it period.
