IMO the way this thread is going is because of the OP's choice of words. "Threatened" is such a loaded word. You can't expect Wii and 360 owners to come out and admit being "threatened", can you?
This is simply flamebaiting. No meaningful exchange can come out of this kind of topic. But I can try.
I am a Wii owner. But before that, I was a PS2 owner. A happy one. I am not beholden to Sony, though. However, I do wish them well. If the 360 can place behind and still make money, why can't the PS3?
I don't feel threatened with the surges of either 360 or PS3. In fact, I welcome it, because it encourages competition. Frankly, I'd like to see a Wii = 360 + PS3 weekly sales, because I think that's the way to maintain a healthy three-way console market. Sadly, I think the PS3 isn't doing it's part to maintain that equation.
The fate of the PS3 does not and should not rest on the fate of the Wii or 360. It's up to Sony to make the machine profitable and to keep its marketshare healthy. Placing third, second or whatever does not matter.
In the same token, the happiness of PS3 owners should not rest on the happiness (or even the lack thereof) of Wii and 360 owners. It's up to PS3 owners to find solace with their already excellent library.
