Are there actually white and gray ps3 out there?

May be...

i have a black one and everybody i know that has one is black also

Japan has the white one and the gray one. The United states has a limited edition MGS4 gun metal gray one, but that is basically gone.

overseas in japan the white ps3 is available. they have it on youtube.

Yes, there is a White and Silver PS3, but they are only sold in Japan.

I don't think they do over here in the U.S. Probably in Japan, though...Japan gets all the cool electronic stuff.

they are gunna bring white one here. im gunna get one

Only offered in Japan. They always get the cool bundles
