Yes, and the trend has been there ever since Sony took total control over Nintendo, and MS made the appearance. It's like Media wants Nintendo to fail. It's pretty unfair.
I think it's a combination of several things, not the least of which being that Nintendo is a Japanese company, and the US media just doesn't like talking too much about Japanese companies in general. Sony is, of course, a Japanese company as well, but I'd bet not too many common people on the street even knows that, and Sony is partially a US company as well, due to it's heavy multi-national presence and the ownership of Columbia, etc. The other thing, obviously, is that Nintendo does seem a bit too secretive. It works for Apple (American company) but it's not really going to the Nintendo's favour, it seems.
The whole thing does remind a bit of the lack of positive exposure that Sega had problem with (again, a
too Japanese company). People often used to say that Sony got free points with the press, etc. but it's just that they built that kind image (it took them years to do so). The kind of image that makes global media write about them. Microsoft did the same over the years, so of course they get the coverage. And when they don't get good coverage - they pay for it and make it happen (yes, MS actually had a whole thing going on with some Ad agency who was secretly mailing media editors and writing positive stories about them during their days of battling with the DOJ, leaked documents in NY Times clearly outlined the whole ordeal)
Now you get to the point that you can only give that much coverage to the gaming scene and you do it to companies that are already more talked about, same behavior kinda maps to PR agencies, and from there to other game publisher high-ups who order their developers what to make games for.
Thats better. You didnt say that earlier. Bear in mind with PSP there are amazingly people who think GBA owners will just dissapear when PSP comes out. According to much of the UK media and games induustry anyway.
Funny as it sounds (and I'll be the first to admit that it never even crosses my mind that PSP can sell better than GBA:SP) I've seen this "sell your Gamboys and wait for PSP" theme being mentioned on in several magazines. True, not in the gaming magazines, but I did see it in some tech/lifestyle/gadgets magazines.
