That list is surprisingly realistic and reasonable.
That being said, I don't necessarily feel that HDMI2.1/4K upscaling is absolutely necessary myself, nor do I think that the hardware budget would be well spent on more internal storage - They'd be much better off including two Micro SD card ports than more internal storage; why waste all of that hardware budget on storage, when they could pump it into making the CPU/GPU better? Or adding a Digitiser to the screen to support an active stylus? Hell, if they wanted people to have more storage out of the box, they could just include a cheap MicroSD card in the box; like they do for the 3DS/New3DS! (Say, 64GB)
The rest are all very reasonable requests that would be very welcome though. Glad to see that they're not pushing for a 1080p screen on the unit (which would be a tremendous waste of both hardware budget and CPU/GPU budget); 720p is the right sweetspot.
