This is kind of a duh. In fact if apple made a handheld and followed this they could win too.I cant help but laugh at those that in this thread said NGP is going to just fail or those that said vice versa. Both the DS and the PSP are pretty good systems. They have both made a profit. Even though PSP is under half of what DS sold it did pretty good.
Lets face it, the PSP did not have one game that had huge world wide mass market appeal. While the DS had tons. The other huge difference is PSP was treated as a home console not a handheld in terms of games. If this holds true again it will be the same results. Though, it does look like Ninty is grabbing some very home console looking third party support too this go round.
I think Sony kinda lives and dies by its third party support. The PSP ended up with just enough of some of the third party games I wanted to play to make me finally choose to get one myself. Funny enough the leader of that is Square the same people who finally pushed me to get a PSOne and two. I have never bought a Sony system for a Sony game. If Sony loses Square support and other JRPG's on the NGP thats the nail in the coffin for me, its also the biggest ninche they fill. I'd assume it would be pretty done period. Different picture for most people who buy a Nintendo handheld, or system period. Good third party support is just one hell of a bonus, but its Ninty's games that tend to make them pick it up.
Im not even sure what market Ninty is going for with the 3DS. Looking at the line up I feel underwelmed atm "except for Kid Icarus" and I have owned every Ninty console. Thats not a good thing. However its the same for NGP, but even less not a single one yet. Sure I see FF listed, 2D Mario and some others id want on 3DS, but no clue what they actually are atm and im not investing in my hopes.
All in all it is a toss up as to who will win in sells. Many things can go wrong for both sides, and many could go right.
