Did Pit mention pixelization? I know Palutena says that at the end of Chapter 8 ("It looks a lot less pixelated than I remember.), but I don't remember Pit saying it.
Regardless, pick it up. With a soundtrack with credits to Yuzo Koshiro, Yasunori Mitsuda, Motoi Sakuraba, and others, that alone is worth it.
Plus, it supports the Circle Pad Pro, which is nice if you're a southpaw like myself.
