Re: Pixelation
It's really just down to C.
A doesn't matter because this is a handheld. No great shock that its GPU trails the settops and desktop PCs. It needs to work under much greater constraints.
B is a given in the original model and thus neither here nor there. The resolution is a constant across both.
It's all C. Existing games were designed to look their best on the original screen. This isn't a new development. Playing games optimized for a 25" NTSC/PAL CRT would have this drawback if a big 36" tube of the same resolution were used. OTOH, you could comfortably play at a greater distance and companies got to sell controller extension cords before wireless took over.
What surprises me is the number of people, including the reviewer, who act surprised the resolution hasn't changed. The price difference is far too small to expect anything else. To produce a higher resolution model with no compatibility issues would require quadrupling the resolution (aka doubling it in each real dimension) in order for the system to scale things up transparently to software. Anything else would produce ugly visual glitches. This alone would make for a much higher price for the screens. Allowing the higher resolution to be driven directly would mean upgrading the innards as well, for yet more added cost.
I'm looking forward to trying one of these out. I have a 3DS but my aging eyes could do with bigger screens. If it feels good I expect I'll get the XL and see what price I can get for my 3DS. If the XL had been released just a few months ago it's probably what I would gotten in the first place.
