I agree with the first part, Nintendo have proven they don't need high end specs to make pretty games. Mario Galaxy and Captain Toad Treasure Tracker, case in point. I'm sure they'll do the same on Switch.

In terms of power though, Switch doesn't look like it will be any stronger for its time than Wii or Wii U were.

I stopped caring about console power starting with the Gamecube/PS2/XBox generation.
As long as the graphics aren't downright bad (blocky, pixelated, murky) I'm fine with that.

Well, yes. Since I'd mainly be using it for bigger titles that are more demanding and I happen to enjoy stable frame rates paired with decent resolutions. Then again; Nintendo almost always beat Sony and MS on frame rates, so that might simply be barking up the wrong tree...

It is important. It is to make sure the more overambitious project at least has stable framerate. BL2 on vita is a really good example for this. I just hope Switch at least can run nintendo 1st party games smoothly, cos the last 2 videos of Zelda:BoTW make me worried

I want it to be a step forward compared to the Wii U because that "new look" feeling you get with a new console's games is important to me. But I was fine with the step up from Gamecube to Wii (2x as powerful) and if the Switch has twice the power of the Wii U I'm fine.

I think this guy's video does put some of the rumored info of the Switch into perspective.

im no tech expert but this could provide a new opportunity for Nintendo, Nvidia, and third parties. Not saying that the power of the switch will match with the Xbone, but processing can be smoother and more up to date than previous Nintendo consoles since they've been running on very old tech (as he said, the Wii U basically uses a CPU that is bundled from old tech from many years ago. I'm not sure if Nvidia is overstating that much.

On a personal level I am fine with the Switch being just as powerful as the WiiU.
Games will look great with WiiU level specs, on a 6" 720p screen, as long as games run smoothly I will be fine.
Whilst I am fine with it being a weak console as long as it is a powerful hand-held, I do not think that would sell very well.

All in all I hope for it to be about 2x WiiU or as powerful as the Xbox one (or somewhere in between).

I'm still going with the 2-3x wii u performance upgrade but you have to factor in the wii u performance was at a very low level. It will not be competitive with ps4 or xbone in either gpu or cpu performance. As crap as the x86 processors in the ps4/xbone are they still will comfortably outperform the arm's of the Switch I expect. It's all a grey area though as we don't know the final spec of Switch but I'm confident Nintendo will compromise it slightly to reach a certain manufacturing cost. I still think gflops performance of around 400 gflops, only 4 cpu's and slower older ddr3 memory or single channel ddr4. If it's shared memory I expect there will be something in the main SOC to provide enough space for the frame buffer plus a bit more, perhaps 32 or 64MB of fast memory, cache etc. This memory may well replace some of the cpu or gpu units.

Clearly Zelda is looking very similar across both consoles so I doubt there is night and day performance differences.

I am expecting cartridges to be smaller than people are expecting so I think there will be some issues there.

It's not going to get decent versions of major third party games. Even if it sells huge numbers its technically much weaker and they don't sell too well on Nintendo platforms. It will be the same situation as wii. Cartridges ensure it will be expensive for third party developers and history shows us such games sell badly so its a non-starter.

Moderately so, as a handheld it's fine, more than fine.

As a home console it's acceptable.... now.

Is it going to be an acceptable home console in 2021? Not a chance.

It's not as bad as the Wii, the Wii was a full generation behind the 360/PS3 and didn't have any kind of modern shader technology that really made that HD next-gen go. 

Switch should be able to run a fair number of PS4/XB1 games, hell the PS3/360 even can (MGSV is still one of the better looking next gen games if you ask me, but it's also able to run on the PS3/360) ... Switch should be more powerful than a PS3/360 without much fuss and has 6x more RAM to boot (if we're talking 4GB RAM with 3GB reserved for games). So a fair number of ports should be doable. Some won't be, probably more ambitious titles like The Witcher 3. 

Don't expect even performance though, things are going to have to be sacrificed.
