Good to see Nintendo righting the ship, if the expected losses were worse. I still don't understand entirely how they can have their biggest hit devices (Wii and DS) still in use, along with "evergreen titles" that sell at full price even though they're not new, AND still get a loss, but I guess that 3DS price cut was pretty extreme. Maybe the Wii U R&D was high too?
I think the importance of smart phones went from understated to completely overrated. Many don't use them to game. Or if they do, they'll only check out a couple pop-culture games for a buck, and quickly move on. In fact, maybe a few get hooked for the first time and actually look for deeper gameplay experiences? Kind of a gaming gateway drug, the way Brain Age and Wii Sports were. "Because of Angry Birds, I'll buy a DS since I now realize I love gaming!"
But I don't think many "gamers" permanently gave up on handhelds, as the button-less and inexpensive experiences - at least for the time being - can only do so much. And "complex" games, the graphically intensive ones, drain the battery pretty damn quick. While that's true of any device, that matters more when you're also depending on that device to do other things such as make calls, play music, screw around Facebook, etc.
Smart phones are sort of a 3rd pillar at the moment, along with console gaming and true portable gaming. There's the ability for them to eventually take over, sure. But there's also the ability for that ecosystem to crash, such as Zynga's recent stock plummet... Along with the realization that $1 games really have to sell TONS of copies in order for them to net the same profit a traditional handheld game "hit" would. Anyway predictions aside, maybe smart phones are eating up the portable share little by little (or a lot by lot), but its nowhere near taking over yet.
Someone earlier predicted the 3DS will be Nintendo's last handheld. I don't think so. In fact, looking at the Japanese trend... If I were to make a crazy prediction, I'd lean toward the opposite. Consoles are sputtering out and I think it would be more likely for Nintendo to stop making dedicated consoles down the line.
Maybe not next gen, but eventually, I think Nintendo handhelds will be playable on the TV and become their "console experiences." The Wii U is almost an indication that this direction is sneaking in already. Suddenly console games can be streamed wirelessly to a portable-like controller. What if their portable games in the future could be streamed wirelessly to the television?
