I used to buy NewType, but now it's sold as NewType (+ "USA version" in teeny letters) and so it's mostly about what's on pay-for type channels here in the USA, and is therefore nearly completely useless for informing me about what's new, upcoming or popular in Japan - i.e, Anime Ground-Zero. NewType USA also focuses on stuff that *personally* I'm totally NOT interested in - like English dubbers or "kinda-looks-like-manga" comic artists in the USA. It's nearly impossible to find a magazine that covers the Japanese markets exclusively, but that's the focus I'm looking for when I pick up an *anime* magazine.
Right now I'm back on websites and Wikipedia for most current info. (Wikipedia isn't fair or unbalanced, or even 100% factual, but it's a good snapshot of what a huge swath of people from a certain set of political demographics BELIEVE to be true at a given moment...) Wiki is also great because it will draw out of the woodwork the 5 otaku on the internet who can collectively remember all seven characters, the seiyuus, and episode plot synopses of some ancient old-school show from like 1983 or something... ...or 1967...
