Thanks for the concern, I certainly hope things return to some normalcy soon. Even though I'm without power and heat, there are many who suffered far worse and my thoughts are definitely with them. I was fortunate to go out and shoot a few photos from the relatively safe confines of the West Village in Manhattan. Here's a link

Additionally, below is one of the photos typical of the "happy hours" before the storm--and before reality hit--where people were out taking portraits with smaller cameras (though this appears to be with something like the Canon S95 series, which I also used and love).
Finally, regarding the SX50, there is an ISO limit in auto modes (at 1600, I believe), and you can set the limit at ISO 1600 or below in the manual functions. You can still shoot up to ISO 6400 (12,800 expanded) in the manual settings, however, and can shoot up to 15 second shots. I haven't had a chance to shoot it at night (maybe I can take it home tonight and shoot some dark West Village photos, but I generally don't take new cameras out of the store!), but in low light conditions around the store it focuses incredibly quickly. I don't have images of those yet, will try and get some up. As I believe I said in my review, I certainly don't expect the images to stand up to an EOS or other DSLR, but where else can you get a zoom like that???
