I'm most keen to try the mouse controls; I'm unsure if I'll prefer them over gyro aiming, but I'd like to give them a go and I can see Nintendo's devs coming up with some cool uses for them.

Not sure yet.

On paper, it's probably the mouse controls, magnetic joy cons, and fixing the speed of the EShop that impress me the most. Basically, a new feature and fixing two of the problems I had with the Switch 1.

Magnetic controls fix the de-sync during handheld issue. This is fixable, but requires some careful invasive cleaning - this, IMO, not the joy con drift, was the big issue I found with the Switch's joy cons. Joy con drift is actually very easily fixable with electronic contact cleaner. There was one other issue with Joy cons (see below).

Larger trigger buttons: the other Joycon issue issue that I see are the L1 R1 trigger buttons sometimes stick or become less responsive, this hit two of my Switches right around the 5 year mark, but it comes and goes.

The EShop was slow and sluggish, had buffering issues with video, and would crash from time to time. This meant that most of the time I'd navigate the library via browser - which was still annoying.

For stuff that wasn't obviously gonna be added probably the mouse controls. Time will tell how much it's utilized but something like Mario Maker 3 could be a worthy sequel thanks to that addition alone. There's obviously the benefit for first person games but it could also benefit a ton of third person ones since neither K&M or a traditional controller are ideal for ones that have you doing stuff like shooting guns since either the movement or aiming is rough.

Gyro helps controllers out a lot with the aiming aspect and this could potentially be even better than that. On PC you can use something like the Xbox Adaptive Joystick and a mouse at the same time but this comes with the system so in terms of controls the Switch 2 could be a contender for the best way to play certain games without needing extra hardware.

In general with the Xbox Series controller being basically identical to the Xbox One controller and the Dualsense not being that different from the Dualshock 4 it's nice to see Nintendo still trying to really innovate with controllers since built in mouse functionality has a lot of potential. Including a couple back buttons on the new Pro controller is another nice feature though since it's on an optional controller it won't be properly utilized so hopefully the next Xbox and Playstation controllers include that so developers can start taking better advantage of those extra buttons.

For me personally 120fps, it was something I didn't expect at all for the Switch 2 but I'm so happy it's there, I feel like the 120fps frame rate will amaze me quite a bit in those games and have the Switch 2 not age as much in the coming years. It's probably gonna be the feature most mind-blowing for me, even more than 4K cause I find frame rate increases more noticeable than resolution increases. 120fps support also confirms to me the Switch 2 is powerful enough to handle all the modern day 3rd party games, making me more happy the feature is there.

Mouse controls seem cool and I definitely like that the controller option is there. I'm just not crazy excited about it yet because I'm not sure how much it'll be used in games for me to play it.

DLSS / AI upscaling is the game changer. Jensen was right.

I actually thought about adding DLSS and raytracing as options in the poll, but I wasn't sure if such technical minutiae were big selling points.

Just happy to have new hardware so we can get more games at 60fps.

Yeah the bump in specs is a very welcome addition for me as well; as much as I love my Switch 1, a lot of games were really struggling on it over the last two years as it was just so far behind in specs due to its age.

It will be nice to play third party ports better framerate and image quality for instance.

On second thought, as well as potentially raytracing and DLSS, perhaps I should have added Game Share as an option.

My girlfriend and I will probably end up owning a Switch 2 each, just as we each have our own Switch 1, so it could be useful to only have to buy games once and then share them to play together.

You should be able to do that anyway with the primary system account thing right? Unless Switch 2 removes that and virtual game card is the only option, Switch 1 they're keeping it as an option. Game Share is one of those things I'm going to have to see in practice to see how good it is, as the game is only running on one console and streaming it to the other I need to see what the video quality and the performance impact is like on some games, and how well supported it will be.

DLSS is looking like it'll be a great feature for upscaling from sub-1080p to 1080p on Switch 2, and as I'll be using it mostly in handheld that's perfect for me so behind the 40fps that's probably my 2nd most appreciated feature.
