Nintendo is the easiest to predict of the three console makers after the avalanche of news from the last Nintendo Direct, where it revealed a handful of potential blockbusters--almost as many as it typically unveils at E3 press conferences. That was out of the ordinary for Nintendo, so we fully expect a calmer Nintendo until E3 this June.
Yes, there might be some game announcements and other news before June, but nothing comparable to January's Wii U bombshells. If Nintendo does something on that level again, the publisher will have few surprises left for E3. However, we wouldn't put it past Nintendo to reveal something that could overshadow Sony's likely reveal of the PS4 in February. Yet, in that case the news would probably be aimed squarely at Japanese audiences, due to the companies’ rivalry being much more serious there.
