Sony

I don't plan on ever switching platforms, it's Sony till death.

So if Bill Gates walked up to you and gave you his fortune in return of switching to Microsoft, you'd rather die?

Nintendo

def nintendo. though between sony and microsoft id say sony

just because you are a big fan , doesn't mean sony have more fans like you than Nintendo

i mean seriously some of the "Not so Gamers" would only get Nintendo consoles because the other consoles don't have Mario or something, how many people you heard that bought a Sony/Microsoft Console just for one franchise?

Nintendo, I dont think its a great thing though.

I payed 599euro (~$800) for my 60GB model with one controller and Motorstorm

So yes the most loyal are Sony fans

I'd rather die.

Apple... they have the triple of insane loiality than any gamer will ever have.

I say Sony because they released a $600 console with few good games (it had some but not many). The first year for it absolutely sucked, but there were some that bought it, it may have not been many, but they were loyal.
