Surely failure of Panasonic to supply batteries for past models (and even current models) will ensure a solid on-going demand for non-Panasonic batteries, and therefore an on-going solid supply of non-Panasonic batteries from Hong Kong etc?
As for AA batteries, I just now decided not to buy a new Pentax Km 2-lens kit at a no-brainer price from Currys largely because it has AA batteries. Li-ion are smaller, lighter, handier, how many more reasons do I need for preferring them?

On the AA Battery front. I used to use a nikon 950 , which had a great swivel back. But it drank AA batteries especially if you used flash. Had to carry loads. It was great in Low light & for candid shots. I'd have hadv to carry 15x 4 AA sets, to do the wedding shoot I did with my FZ28 with 3 x Lithiums. Shot over 1,300 shots + video because each battery lasts for about 460 shots. It really takes the enjoyment out when your worrying about the batteries running out. Also didnt have to use the flash as much as it worked so well in natural or low light throughout the wedding proceedings. Ive tried high capacity rechargeables ie 2700 & up but I still need loads if using an AA camera.
I found it expensive, to spend about £4 to get an emergency battery supply, when the AA's died, so over a few yrs ownership, the 1 panasonic battery that comes with the camera, works out much cheaper to run. Bit like a cheap printer, with low capacity expensive cartridges vs high capacity printer. Both do the job but 1 saves u megabucks to run.
Thats why I dont use my AA Canon Powershot sx110 except as a backup, & the fact that the colours are not as good on the final print. I also noticed its not very sharp compared to the Panasonic.
I love the fact that the FZ cams share the same battery , so in our family where we have the FZ38, FZ18 , fz28, (Leica v-lux-1) FZ50, & my cousin has the FZ30 for wedding photography &, we just lend each other our batteries, SD cards and compatible batteries for big shoots. It doesnt matter which cameras battery was in which camera originally. I was so happy that the FZ38/ 35 I bought last month, shares the same batteries as the 4 yr old batteries. These batteries are the longest lasting batteries I've ever had in a camera ie nearly 500 shots, which is fantastic & I havent had any of the 4-5 yr batteries die on me yet.
