LOS ANGELES -- Nintendo closed out the parade of press events ahead of the Electronic Entertainment Expo with its own live-streamed presentation detailing plans for its Switch video game console. The focus of their stream was all Switch, revealing several details on upcoming games for this holiday. Nintendo's icon will arrive on the Switch console October 27, which means fans of the publisher will get a new Zelda and Mario game in the same year. But let's get to the game itself, because it looks spectacular. It's a "sandbox" style game, which means Mario can go anywhere and explore.

Xbox chief Phil Spencer speaks on stage at the Microsoft Xbox E3 2017 Briefing at the Galen Center in Los Angeles, California. The Electronic Entertainment Expo (E3), which focuses on new products and technologies in electronic gaming systems and interactive entertainment, takes places June 13-15 at the Los Angeles Convention Center. LOS ANGELES -- The show floor doesn't open until Tuesday, but E3 has already kicked off. On Sunday, Microsoft was the first of the three video game console makers to hold their annual media event ahead of the Electronic Entertainment Expo. The highlight was their hardware, but there were some other interesting details unveiled by Microsoft. Prepare to hear this a lot between now and November 7: "the world's most powerful console."

A complement to the OneDrive on Demand feature coming in the Fall Creators Update, Microsoft's also adding offline folder support to the OneDrive mobile apps. If you download a folder and make changes while you're offline, they'll be uploaded to the cloud the next time your device connects to the Internet. You don't need to wait to start using this, though. OneDrive offline folders are already available for Android to Office 365 Personal and Home subscribers and OneDrive business accounts, with iOS support slated to roll out in "the next few months." Just click the Parachute icon to save a folder offline.

The new console can be played on a TV or on the go. On Thursday, Nintendo finally offered an in-depth look at the Nintendo Switch, its next video game console launching in two months. The Switch is a home console with a tablet at the center. It can attach to a docking station connected to a home TV, or travel with players by connecting two remote-like controllers called "Joy-Cons." In case you missed Nintendo's event Thursday night in Tokyo, here were the five biggest announcements: It will launch on March 3 worldwide for $299.99.

Google's finally interweaving the deep treasure troves of information it holds about the world at large and you, specifically. Google Assistant is a conversational digital assistant built around the company's strengths in deep learning and natural language recognition, summoned at an utterance of "Ok Google" to respond to any queries you may have. It can understand context depending on the topic at hand, too: Holding your camera at a famous sculpture and asking "Who designed this?" will get an answer, as will queries like "Show me his other movies" after asking something like "Who directed The Revenant?" Google Assistant will be able to play music playlists, file reminders, help you buy movie tickets, and a whole lot more. Interestingly, it doesn't appear to be a discrete app; instead, it appears tied to be baked right into Google-y gadgets, in what Google CEO Sundar Pichai calls "an ambient experience that extends across devices." Think of it as a supercharged version of Google Now, mixed with Amazon's Alexa.

Cortana, the personal digital assistant baked into Windows 10, is about to get more powerful and even easier to converse with. Microsoft's building more utility and contextual awareness into Cortana, including more proactive actions where she offers to perform tasks without even being prompted, and putting it all at your beck and call with powerful natural language tools. A quick pair of demos by Marcus Ash, the group product manager for Cortana at Microsoft, drove home how useful the new skills can be. In one, he asked Cortana to "send [a colleague] the PowerPoint that I worked on last night." This seemingly simple command is actually deceptively complex; to fulfill it, Cortana has to know what PowerPoint document Ash was talking about, when he was using it, and who the colleague is.
