Will be interesting to see what the performance is actually like in real world scenarios. I am concerned with the extrapolation and, in my opinion, frequent romanticism based on apparent "leaked" specs usually by people who don't have a lot of technical knowledge. A lot of throwing numbers around without appreciating their meaning and the complexities involved, along with whimsical to-the-metal programming romanticizing. End of the day the capacity for hardware performance and nuances of programming is a logic driven exercise, not magic, and there are countless factors that need to be considered as to why games look technically and artistically the way they do, and what limitations they may be running into. Comparing two titles is quite often a distinct apples/oranges example, and honestly I think even then some people just don't have an eye for or get why one game may not "look" quite as good as another but still be intensely technologically demanding.
Ultimately, with the Switch, I'm operating under my thumb rule to err on the side of caution. Throwing around speculation is all well and good, but Nintendo proved quite blatantly with the Wii, 3DS, and Wii U that they took an extremely conservative approach to hardware ceilings. And in all three case (notably with the Wii U) there was a lot of pre-full-reveal optimistic speculation regarding the size of the case, what could fit in, modern hardware, etc. And it turned out that Nintendo went cheap as fuck.
Same goes, in retrospect, all the talk about magic efficient programming and yadda yadda. The reality is many of the Wii U's most insanely gorgeous games, like Super Mario 3D World, are intelligently made; basic geometry, clever reuse of assets, simple game systems not overly demanding. And even then they're hardly flawless.
If anything the Switch's advantage will be, hopefully, modern architecture. In that the hardware is more reminiscent of modern hardware and thus offers easier opportunities for developers to consider porting games as while they might need to be heavily downscaled in asset quality and shader complexity the driver library and hardware will hopefully avoid major hurdles in trying to get modern programming language up and running.
That being said I'm still expecting a system that, even when docked, is a noticeable step backwards from the PlayStation 4. Docked performance makes perfect sense as it's something portable hardware (namely laptops) has being doing for a long time. Even so it's still seemingly quite a small device. They'll save space by not having a disk drive, but yeah.
That and I do not expect Nintendo to double down on an expensive device. Factor in costs, like the screen, that other consoles do not have and Nintendo will find ways to cut costs elsewhere.
