Games pricing is definitely limiting 3DS possibilities in the US market. As well as the lack of Platinum / Player's Choice likes at retail: I'm so sure Nintendo titles (and some third parties) would see good increases by putting older titles at lower prices. But I'm also one of those who firmly believes that the pricing system in general is hurting lots of titles in the overall market, especially new IPs...that's why I accept open-hearted Nintendo intentions of making pay you less the more games you buy. I've even opened a thread about it, since it's one of those things that seem to be talked the least from last January, but IMHO could be great (again, as executed well), and for which we've already had some tests, and we're still seeing them. Hopefully, they do it right and they include retail purchases as well.
I don't know what the point of that would be. People aren't going to buy a Nintendo phone. Unless you mean it will also run Android, which I don't really see either.
Before I forget, I promised you this
Here's the sketch I draw some months ago, and that I already posted on Gaf in various occasions.
As you've already noticed, actually this is a concept for a console that can be a phone (turnable screen for the top part) and a tablet (rotating hinges + retractible L & R buttons with a support, like the Wii U Gamepad), but just remove the whole tablet part, and it still stands for what I was meaning: something that can be used as a phone, but that's an handheld at its core.
Such a design would also implicate a cost advantage (only one photocamera, instead of two, since you just need to rotate the screen part in order to make photos internally or externally) and a neaty feature (with the camera outside, who shoots uses the bottom screen, while who's being shooted could actually check if everything's ok with their own eyes, by looking at the top screen, rotated towards them; the same for videos).
But, while I'm sincerly excited for the prospects of Nintendo Network being their actual platform, I'm not so confident they'd have what it takes to develop such an hybrid, especially on the phone front, where they have no experience currently.
Apart from this (very) hypotetical scenario, my beliefs for next Nintendo handheld are currently
1)3D out
2)still two screens, this time both capacitive
3)launch price lower than 3DS, but not super-budget right out of the gate (around 199.99, and not higher)
4)powerful enough to
- support as much tools as possible for indies / little developers(like Wii U, if not more: Nintendo Web Framework, Unity Pro, Construct 2, and what else will come)
- get some historically "home" properties from Japanese third parties, at least as multi releases: Vita risks to have no successor, so some of its franchises should go to Nintendo's next handheld, but they should try to get some other franchises that are not so used to release on portables. Mentioning Japanese third parties since they're the ones who could probably be more interested - I'd like to see Western third parties throwing some multi bones, but that's quasi-impossible right now
