Wrong. CheatHappens makes trainers for the Nintendo Wii.
So yes, it is possible.
Of course it is possible.
All 3 major consoles can have trainers done for them. With the PS3 jailbreaked etc it is very very possible now.
I remember there were trainers for PS2 by running them on disc. I hope there will be same solution for PS3.

Trainer for X-Box?
I dont think there are any trainers available for the X-box currently.
