I don't like the "new" moniker either. However, I'm quite excited for this.
+MicroSD Support will be nice, and the new location means I won't be getting gunk jammed around the door for it.
+I don't really care about the NFC stuff, but neat!
+Improved battery life, very yes!
+I don't know what "Super Stable 3D" is exactly, but as I understand it, it involves improvements to the 3D.
+Improves the 3DS to have the 3DS XL's curves, which means no more corner prints in my palms!
+Moved the game slot to a new spot. Okay.
+Improved display size! (If it hits the DSi's screen size, I will be very pleased.)
+Better browser (not that I used it much, but good to have, especially if it's faster.)
+Wireless PC Backup support? Intriguing.
+More RAM and VRAM? (So I've heard)
+Improved cameras (So I've heard)
+Something about a gyro? (Is it an addition, an improvement, or the old one?)
+Faceplates, meaning that you don't have to ditch your current system for a special edition one - Nintendo's special edition systems will likely just have special edition plates, meaning ease of repair and replacement, and more design and customization possibilities.
*Not sure I like the locations of the ZL and ZR buttons, but good to have more inputs.
*Not sure I like the location of the new analog nub, but I'm glad it's there.
Here's what I'm hoping for:
*Improved experiences on games that currently have slowdowns (e.g. Pokemon X/Y)
*Faster access and traversal of the eShop and MiiVerse and internet browser
*Improved parity between the Wii U and the 3DS in terms of eShop titles (At the very least, making GBA games and SNES games available on the New 3DS, or better yet, buying a title on one system makes it playable on both, like the PSN... at least, please, give us the ability to share our saves back and forth between the Wii U and 3DS) (I wonder if this PC backup thing will give you anything like that, or if it'll only be for photos.)
*Continued support for DS games
*Improved 3DS/Wii U connectivity in general
I really hope that this is a strong step towards a future where Nintendo breaks down the walls between their consoles and their handhelds and unifies the future. The efforts in merging and simplifying the eShops, Club Nintendo, unifying the Nintendo Network, and creating/unifying NNIDs are steps in the right direction, but progress has been slow and they're still years behind Sony. With Microsoft's blunders recently, this would be a wonderful time to step up and give the world some of the things they've been begging from Nintendo for years - and I think that the improvements to the 3DS may well be steps in that direction. With the New 3DS adding two shoulder buttons and a second stick, it now matches the Wii U game pad for inputs (minus the analog clicks, probably). In that case, it could conceivably be used as a Smash Bros. controller for the Wii U, or for other games built to support it, allowing all players with a New 3DS to enjoy the input options available to the player holding the Wii U gamepad, rather than being sad and stuck with an old and limited Wii Remote. It could allow games to be built for both systems with a minimum of control style changes, allowing for a PSN "cross-play" of sorts - something there's already precedence for with MH3U. Heck, it could be even easier if they let you continue using your handheld as a controller and sync the play to the big screen through the Wii U.
If Nintendo plays their cards right... makes the New 3DS desirable enough by feeding it must-play titles, makes it a potential controller for Smash Bros. and/or other titles, and implements Cross-play to a greater extent, it could revive the Wii U and pave the way to a stronger, more unified Nintendo ecosystem of the future. Just selling these new systems might give them the cash flow they need to push on into the future and make some of these dreams a reality. C'mon, Nintendo. Please?
