I got now 3200$ and don't now what to do: buy camera now or wait for next generation cameras?
Your advice please!!!

Depends on your needs. Do you have a lot of projects pending? Anything that you couldnt rent cameras for until you feel like the next gen is here?

I am assuming by next gen you mean HD. Thats the only case you should really make, because there will always be a next gen on the horizon. You should get a cam when you need a cam, because there will always be a better one next year. Even with the HD cams out now and on the horizon, they are either HDV (which feels kind of like it will be an intermediary step), and the first gen HD prosumer cams. Subsuquently, even if you waited for them to hit, youd still feel like you missed the boat again, a year later, when the next wave of cams hits. Thats just the way it works. You have to but a cam when you need one, not want one. Rent until then, and you'll probably be happier in the end. Whatever you do, if you do decide to buy a cam, dont buy it until very close to when you'll start shooting - enough time to get acquainted with it, but close enough that you'll catch any price drops on the way.

Jeff, thank you for reply.
My English is very bad, but I hop that you’ll understand something.

I don’t need to buy camera immediately. I’m not a filmmaker, who has film projects. Basically I want to become one of them, but for now I want to start make some short films. Good films. And for this I think that I need good camera.
The thing that I care more about in cams is image quality. If HD cams will be too expensive and image quality not much better, then I believe there is now reason for waist of money. But this is where I stuck, I don’t know almost anything about camera’s technology and if there is a big difference in image quality from other types of cams.
If you now something, please tell me.

And maybe you know some really good books or links about film directing?
