The 2015 Consumers Electronics Show officially began today, Jan. 6, but many of the world’s biggest tech companies held press conferences on CES’ “Day Zero.”

Announcing some of the coolest, ambitious, and expensive ideas and items in technology, companies like Samsung, Sony, and others showed their vision for the future over a day of press conferences.

What does it look like? Find out with some of CES 2015‘s biggest reveals.

1. The house of the future. Samsung is hoping to be at the forefront of the “Things” part of the vaguely named “Internet of Things”—which may sound like a lame sci-fi dystopian novel, but is actually a silly name for a trend much of the tech world anticipates.

The company, which gave the CES keynote this year, envisions a not-too-distant future where everything in your house—even items that wouldn’t normally have technology integrated into them—will speak harmoniously with one another. And Samsung promises all of its Internet of Things products will not just be able to talk to each other, but will be open to talking to other company’s items. That way, consumers aren’t locked into buying only Samsung-branded products to decorate their homes.

The Verge has a deeper explanation of what exactly Samsung’s plans are for a future where everything from your fridge to your chair to your lights will operate in unity—and hopefully not rise up against you like Skynet.

2. All this car’s missing is the ability to hover. Mercedes’ newly revealed concept car (pictured above) may have a goofy name—the F 015 Luxury in Motion—but the self-driving car is a promising and sleek attempt at a hydrogen-powered car. The F 015’s four seats rotate to allow fellow passengers to interact more directly with each other and the car’s many gadgets, while LED lights on the front and rear of the car denote whether it’s in an automatic or manually driven mode.

3. Internet TV will make you consider cutting the cable cord for good. Dish Network announced Sling TV, an Internet cable package that will allow subscribers to pay $20 a month for a host of popular TV networks, including The Disney Channel, The Food Network, TBS, TNT, and ESPN. Broadcast networks are not included, but subscribers will be able to buy $10 add-on packages for specific genres of programming.

Meanwhile, Sony’s previously announced PlayStation Vue service—a similar Internet TV package—is scheduled to arrive in early 2015. The service does include networks like NBC, Fox, and CBS, as well as several others, and has previously been in an invite-only beta.

4. Video game controllers, roll out. This video game controller, as Kotaku aptly notes, is essentially a Michael Bay-styled Transformer that, rather than destroying or saving mankind, is just a cool-looking way to let players destroy or save virtual mankinds. The L.Y.N.X. controller can connect to PCs or works with Android tablets measuring up to seven inches, and will ship from Mad Catz some time in March for $300—about the price of five Xbox One or PlayStation 4 controllers.

5. Tony Hawk’s Advanced Skatefare During Sony’s press conference at CES, Tony Hawk came on stage to demonstrate the Sony Action Cam with 4K video, but for video game fans, he brought something even more important with him.

Hawk announced that a new fully fledged skateboarding game is in development for the PlayStation 4—and likely other platforms that Sony would not want mentioned at its own conference. He promises it’s set to release this year and is “much further along than I imagined” in its development.

Hawk appears at about the 44-minute mark of the conference, and specifically discusses the game at about the 49-minute mark.

He had no details to share, other than that it would have the initials “T” and “H” in the title, referencing his line of Tony Hawk’s skating games that began with Tony Hawk’s Pro Skater back in 1999. After a few attempts at bringing the franchise to phones or forcing players to actually use a skateboard deck to play, his next title could return the once-beloved franchise to its wackier—and much more fun—roots.

CES 2015 will continue through Jan. 9.
