Wii U, 'Halo 4' boost anticipation for E3 - CNN.com (click for full article) (CNN) -- For a preview of the next big thing in video gaming, look no further than the Electronic Entertainment Expo, the splashy industry showcase that kicks off Monday in Los Angeles. Will it be the oddly named Wii U, Nintendo's attempt to update its aging Wii console for a new wave of gamers? Or "Halo 4," the next chapter in the massively popular sci-fi action series? Or maybe a surprise device or game that comes out of nowhere to captivate attendees? This year's E3, as the annual trade show is better known, arrives during a time of upheaval for the multibillion-dollar gaming industry, which is scrambling to adapt to changing consumer habits. While home console gaming remains huge, more and more people are playing casual or social games on touchscreen phones and tablets. "I think we may be seeing the last generation of dedicated handheld gaming systems with the PS Vita and Nintendo 3DS," said Blair Herter, co-host G4TV's "X-Play." "What we've seen is the mobile gaming space really take over what used to be considered the handheld gaming market." Many analysts, including Herter, think this year's E3 won't have as much bang as previous shows. Herter said he thinks this is because of expectations for next-generation consoles being developed by Sony and Microsoft for release in 2013, and game developers' hesitation to make something that might have a short shelf life. As an industry-only event, E3 is geared toward gaming media, developers and insiders. But in an effort to reach out to the public, many companies will be streaming events and shows throughout the four days of the conference to give fans early glimpses at new games and let them hear from developers directly. The E3 show floor doesn't open until Tuesday, although festivities begin Monday with press announcements by Microsoft, Sony and several game developers. Here's a roundup of what to look for: The Wii U, ready for its closeup Most companies at E3 will be showing off what their existing hardware can do or emphasizing new video game titles. Nintendo is the only one of the Big Three console makers -- a trio that includes Microsoft and Sony -- that will be demonstrating a new gaming system this year -- the Wii U. While the Wii U was previewed in more primitive form at last year's E3, there have reportedly been some changes in how the console looks and what it can do. Official word has been hush hush, which is typical for Nintendo before a big announcement. However, some images and news have leaked out suggesting the touchscreen controller for the Wii U will be different from what was shown last year. There has been some confusion about whether the Wii U is just a new controller or a more powerful console. Nintendo hopes to clear that up next week by demonstrating a "final" version of the system with games designed specifically for the Wii U. At last year's E3, Nintendo showed a Wii U video demo featuring gameplay from Xbox 360 and PlayStation games. Pricing remains a mystery for the Wii U, which is expected to go on sale in fall 2012. In April, Nintendo chief executive Satoru Iwata said a price for the new console would not be announced at E3, but that the company would reveal its initial lineup of games. Some industry analysts think Nintendo needs to announce a price at E3 to generate buzz for the console.
