Not to be a dick or anything, but even Microsoft learned that "X-Treme" was out dated within the first month of their XP Advertising ventures in 2002.
Err..XP stood (and still stands) for eXPerience, not anything "eXtreme". They tried to sell Windows based around a brand, rather than on version numbering. Whether or not that worked out for them or not is up to you to decide - after all, the upcoming version is branded "Vista" rather than being version numbered.
All Microsoft changed during the XP period was the "Home"/"Professional" tags. With the introduction of SP2, you'll notice your computer merely boots "Windows XP", not "Windows XP Home Edition" or "Windows XP Professional Edition". Anyhow, I'm getting off track. "eXPerience", not "eXtreme".
It just seems to me, that if starting a new company, a little bit of market research on product name should have been done.
What's in a name? Who are you to decide from your armchair soapbox that the name of the product is inadequate, or that they haven't done any research? There's nothing particularly classy about M3 (Movie Player 3), G6 or Ewin 2, just for a few examples. Since the DS-X is going to be abbreviated just like that, what's the problem? As long as it works in multiple languages and doesn't mean anything silly or offensive (
remember the Chevy Nova? In Spanish, No va = doesn't go, and that certainly isn't something you want associated with your car) then there really isn't a problem. If consumers will get excited about and purchase a Wii, I'm sure the DS-Xtreme will be just fine.
Note: I know doodly-squat more about the product than you or anyone else, and I care doodly-squat as well. There's just no need to harshly criticize something that hasn't even been released yet, and for the name no less. Everytime I see a product criticized on name alone it makes me cringe. I think the iPod is one of the stupidest names on the planet, yet they're so prevalent people use it in place of 'MP3 Player'. In the end it's not the name that matters, but whether or not you can generate the necessary faith in your brand (by having a good product) that will encourage users to buy it.
