call of duty modern warfare 2 beta for ps3?

Ive seen some videos today about modern warfare 2 coming out with a beta for ps3. If youve seen the trailers and other videos you should know they are for xbox 360, I know because when someone has to reload their weapon it says X which is the xbox 360 control for reload.

So some people think theres a ps3 beta and making videos on youtube, but those are all fake, there might be a beta in the making, but Im not sure.
