For the last time, launching DSi isn't the same as launching a Wii-HD, people!
DSi is portable! If you have a DS, you can buy a DSi and give the old to your lil' brother! If you happen to break your DS (like if it fell on stairs), you can buy a DSi. Portable means, as Nintendo always try to say, one machine PER PERSON.
Wii, PS3, X360 don't work this way, it's one machine PER HOUSEHOLD. If you have just bought a Wii, will you buy a Wii-HD just because it's HD? Really? You just wasted a lot of money.
There won't be games for it. Nintendo would crack it's install base. 3rd-parties won't make games into a platform that have only a handful of owners, when the prior is the fastest-selling!
So, they will make a lot of HD-less games, and... you bought the Wii-HD because it's HD, right? So... "WHERE ARE the games?" You scream. Sorry... there WON'T be games, and you just used a few hundred to buy a gaming machine that can play your old games, but wait! Don't your old gaming machine do the same?
With DSi it's different, you don't buy it 'cause it has a better graphic. You buy it because it has a camera, it can play music and because it's a trend. Or... like I said... Just because you lost/broke/gave your old DS and you can afford to pay a little more to have all those new things.
With that said, we can infer:
EVERY DSi-only game you buy is a PLUS. You are neat!
EVERY Wii-HD-only game you buy is a need!
Do you see it? The DSi is safer to third-parties, the Wii-HD is catastrophic, it's an all-out strategy that can ONLY WORK within a whole new generation.
EDIT: I just read this "Microsoft tends to name its internal projects after cities. Natal is a city in Brazil, which is where Alex Kipman, one of the key engineers on Project Natal, comes from. What Mattrick and Kipman decided to try to do was to get rid of the controller altogether. They wanted a technology that would enable a gamer to control the game just by moving his or her arms and legs and other body parts. The gamer would become the controller."

Yey! I live at the same town! hahaha! Didn't know that Alex Kipman (the name doesn't help) came from here. wow!
"How hard would it be to randomize facial features and skin tones? That's what we want, to feel like we're killing hundreds of different people. Not a bunch of clones or twins. We want to know, deep down, that there are hundreds of grieving mothers out there, lamenting the terror of our dreaded blade."
