What makes you think that ?
What makes you think that nintendo would be unable to release an hidef gaming machine after the Wii ? If the Wii happens to be a failure, nothing would prevent Nintendo to shorten the Wii lifecycle, like Microsoft did with the Xbox. With the massive cash reserves they have they could take some blows for sure.
people, in the USA specifically, are lazier now than ever, after a while people will grow tired of the novelty of moving around to play video games and will want to "just play the game" instead of getting a workout to play, it's just the way it goes here, we want to have fun and have things without doing anything, the part that requires physical movement other than finger twitching will get old, trust me, it will happen, the DS did not have that aspect, the jump around to play a video game aspect, so it is not a fair comparison, and personally, the PSP is more interesting to me than the DS
i never said Nintendo couldn't do a HiDef system, but i dont think they will, i think if they were going to it would have been now, i think they were trying in a parallel project and it was going to be too difficult/expensive to bring to market so they abandoned it and for PR reasons decided to say things like "we aren't trying to compete with the PS3 and 360", so they wouldn't look so foolish for releasing 2001 graphics on a 2006 console, but look, we have.......the Wii Remote.....cool huh !?
also i am sure the tried and true game developers in their corner were probably not wanting to cooperate, telling Nintendo it was too time consuming and costly to rewrite all those games to run 720p or 1080i resolution on an entirely new system.....hey, we got an idea.....lets do the retro thing.....take the Gamecube, make it what we really wanted it to be years ago, add a "revolutionary" motion sensitive controller, give it an "Ipod'ish" look and market to people who have been buying all these old Nintendo, N64, Super Nintendo and Genesis games over the years, and make them want to buy them all over again.....yeah, no R&D costs for the game devs, no risk, just put the same old games up for sale again to be downloaded on the Wii.......little cost, little risk, pure profit for all
personally, i have like zero interest in playing the old classics, i thought i did, and then i tried downloading a few of the old games over XBL, and even upscaled on my HDTV through the 360, the games still look like crap, play like crap, sound like crap, etc.......used to be an avid Grand Turismo fan as well, tried hooking up the PS1 to my TV and guess what, i nearly puked thinking the whole time.....i can't believe i actually used to enjoy looking at this crap
while many of you guys may try to take the "graphics isn't everything" road, i am here to tell you, that i have a 360, it lets me do so many things the Wii cannot allow me to do, it allows me to play games in HD glory and still have good gameplay, there's nothing wrong with the best graphics in town as long as the gameplay is up to task, and it is for me with the few games i have bought, the graphics could be awesome, but if the gameplay wasn't there, the game gets gone, this happened with MotoGP 06, too difficult, too hard to play and enjoy, looking good wasn't enough, so it's not like i base all my opinion on graphics, but if i and the rest of the world with HDTV's can have good games and good graphics too, dont expect us to lower our standards to 2001 graphics in order to jive around with a Wiimote in 480p glory.........
