I originally thought to do a detailed comparison of the New 3DS XL with the current 3DS XL, but realistically that information can be found elsewhere with more detail than I can be bothered with, so instead here are my quick thoughts.
Quick summary of the important New 3DS changes
Faster, New ‘c-stick’ button, New ZL and ZR buttons, Improved 3D, Change in button/slide/card slot locations, fully compatible with all existing 3DS and DS games
How does the 3DX XL physically feel?
It is close enough in weight and size that you don’t feel a difference when switching between them. The finish is a finger print magnet but feels a bit more grippy than the existing standard 3DS XL.
Is the speed make much difference?
Yes, a huge difference. It starts up faster, launches games faster, goes to the home screen faster from games. If you are someone like me who is constantly closing/opening the 3DS, then it’s a lot less painful to use. It may be just me, but the existing 3DS XL seems to be getting slower, especially when using themes.
How good is the improved 3D?
The 3D is now 100% usable, the new 3DS tracks your face and adjusts the 3D accordingly, and it works really well. So if you were someone who never used 3D because you didn’t have the robot like capability of holding your hands and head dead still for hours on end, then you are in luck. It has made me re-visit some older 3DS games so I could actually play them through in full 3D. It even works in the dark, using infrared to track your face.
Is the screen any different?
The screen is the same size, resolution and quality as the existing 3DS XL, but now can do dynamic brightness adjustment which works quite well especially when using outdoors.
How’s the new ‘c-stick’ and ZL and ZR buttons?
The new c-stick is very comfortable to use, and in a very convenient location (works great in Smash Bros). It also can be used as a replacement to the Circle Pad Pro, which made existing 3DS XL into an hulking beast with weird weight distribution (much like myself). The ZL and ZR buttons are perfect for my overly long fingers, and can be used in the home screen to scroll left and right which is nice. I can image that there location could be painful for people with smaller mits.
How about the other button/switch moves?
The home button is now raised in the bottom center of the bottom screen, and the start and select button are also small raised circles below the A/B/X/Y buttons, because they are no longer immediately adjacent to each other you don’t accidently hit the wrong buttons, and because they are raised it makes them easier to locate in the dark. There is no longer a wireless switch, it’s software instead, which means that I no longer accidently turn it off in my pocket or bag which is cool. Volume control is now on the left hand side of the top screen, which again means it doesn’t change in the pocket/bag. I’m unsure about the new location for game card being on the front, I’ve had it pop out accidently a few times which doesn’t happen for me very often on the existing 3DS.
Quick Round Up
Lots of small changes, all amounting to a better all round experience. The speed and improved 3D alone are good reasons for trading up. If you are a big existing 3DS XL user, or want to actually use the 3D all the time, then I would say get one. Eventually you will need one to play new ‘New 3DS’ only games, such as the great Wii game Xenoblade Chronicles, which will be a New 3DS only game when it comes out. There are rumours in the web-o-sphere that Zelda Twilight Princess (GCN/WII) and Mario Sunshine (GC) are also on the way to the New 3DS, which would be very cool if true, as they are both great games.
