It means three things that I can see:

Nintendo is raking in the cash and dominating the gaming industry (not news).

Sony still has a pretty big slice of gaming revenue due to their diverse hardware and software product line, they just aren't doing a good job of controlling costs to leverage that revenue into profits.

Despite showing strong sales growth, Microsoft's narrow hardware and software product line have kept their (console) gaming revenues relatively low. Like Sony, they also aren't successfully turning their revenues into profits.

Sony would be making some killer bucks if PS3 wasn't digging to the center of the earth.

Look at the number of employees Nintendo has. Very small for the amount of revenue they have coming in. That has to keep costs down, even though they are spreading the love financially all over the company.

Oh right, only SCE. Yeah, that makes more sense.

It is "Nintendo is." There is not more then one Nintendo. Nintendo is a single company. When I say Nintendo, I mean the one corperation that makes Mario, the Wii ect ect. How are people thinking it is plural.

Companies are singlular people.

Nintendo is made up of multiple divisions whom are all making money. 

he always does that, every sony thread look at the first page and you will see him posting something unrelevan about 360.

ps3 slim? 360 slim will destroy it!, it makes me laugh, poor soul.

any way i am trying to give you my money sony. accept my damn visa, we even use dollars HERE come on.

Your body is made of multiple divisions. Doesn't mean I call you "they." A building has mutilple floors and many different opperations (some of which are making money). Do I call it "buildings?" Nintendo is a single company. I can say, "Nintendo has many divisions. They run well so the companmy can make money." The divisions are plural, yes, but the company itself is still singular. Again, unless you can find me multiple Nintendos, then it's singular (and this doesn't mean NoA, NoE ect. They are part of a whole).

Small grammar sidetracking: I understand that with collective nouns you should always use them as singular when you're thinking of the group of a whole entity, you can use plural when "group X" stands for "the people that form group X".

Example 1: Nintendo IS a japanese company. Example 2: I know that Nintendo ARE going to introduce an "autoplay" feature in SMB Wii

Even on the BBC I hear them using plural verbs with "the government" all the time when they mean its members - and I assume their is a good, urban English.

That said, James T. is wrong here - and we should never lose an opprtunity to rub it in.
