Matthew Gallant, of the site gangles, has typed up the history of the famous A and B buttons! Taking a look at Nintendo, Sega, Microsoft and Sony.
It starts from the revolution that was the NES controller with the break away from the joystick fad to the DS where the article's author was shocked to find it A and B instead of B and A. Though the basic functions have been kept the same, designs have changed. Sega and Microsoft consoles have been similar, also using the A and B theme. Yes Sony is in there too, they may look different but X and O do the exact same stuff when you think about it!
A is your positive, B is your negative... or something like that. Anyway, the article describes the design of each console and the evolutions over time.
So remember kids, it used to be B before A in the alphabet of video games.

Only thing different, is the colour co-ordination. Same colours, different buttons.
ABXY are good letters. i just realised after reading this that those are also the letters that are 90% of the time used in equations or just more commonly used as variables.
they are used in phyics as well.
/_\X = Change over the hor. axis
/_\Y = Change over the virt. axis
A = Acceleration (motion)
you get the idea.
I believe Sony wanted to differenciate themselves. In part because the Playstation was born out of a failed joint project with Nintendo. And in part because they just wanted to be unique. Doesn't matter though as long as it works and gets the information across.
I did find this history of controllers a nice red though.
