Halo can be played on PS3?

Can Halo be played on PS3? Some people said yes while others said no. I got confused. Anyone can prove this?

They say it can be played on PSP, but your memory card must got big space to play. weather it can be played or not, for me it can.

Ok.... to clarify things....

1) Halo is created by microsoft. Microsoft = Xbox. Sony = PS3. So no way
2) You half correct and half wrong sotsot. You can play halo on PSP but it is not official, meaning it is created by hackers. So it will be very sucky and not realistic at all. And from what i remember, the halo game for PSP is only 50-150 mb
