There's no doubt the GH3 is going to a hot seller. In fact it's already shipping, but out of stock everywhere you look. Today I got confirmation that one store in the USA has a few available, and they've listed some inventory online for a small $190 markup over suggested MSRP. Can't blame them. Just business on a hot commodity, and at least they are including a 'MACK Diamond 3-Year No Fault Warranty' if that means anything to you.
So, If you're dying to get one I wouldn't think about it too long, because it will most likely sell out even with the small markup. You can find the new Panasonic GH3 camera listed via eBay (click here).
