Its said that to make a product a success you need to win the hearts and minds of the customer. I think its fair to say that as a design Revolution already captivates, yes in pictures it doesn't really shout, but once people actually see the DVD case size glossy machine with a neon, well its got that special something. Turn on RED STEEL and actually show people the controller in action, I think their hearts are won. Then of course the machine will be cheaper, the games will be cheaper and the online gaming will be free! Where is the catch...its a Nintendo machine. I think thats easily gotten over actually, stop showing mario on every internet page and customers might not feel so alienated.
Number 1 in Japan looks in sight I think, but thats just judging from DS vs PSP.
America, things are very interesting, you can't judge from the handheld wars because neither are selling very well, the GBA SP still reigns supreme apparently. Like some1s already said, the economy suggests nothing will do well, unles price makes any difference (points for Nintendo).
Nintendo of Europe seem to have manged to get thier act togather for the DS launch. No one could not know it was launching and there is still frequent advertising. Although they've sorted the Official Magazine, that damned web site remains with its bubble writing. Not really set for a market other than Nintendo's core. It still feels in Europe like Nintendo are only here on weekends unlike Sony and Microsoft who seems very settled with developement always going on in EU countries. This could be quite significant.
The PS3 is not a mass-market product, its too geeky, bulky and expensive. Xbox 360 is only targetting young males. The only product that can exite everyone is Nintendo's. If they use their advertising budget wisely and make some MAINSTREAM (ie. not GamesTM) headlines then Revolution could sell the most.
