PS4 rumor roundup: Streaming? Competitive price? 4 unlucky? Sony has been keeping the contents of its Wednesday PlayStation announcement tightly under wraps, but the rumor mill has been churning, and besides a new console - dubbed PlayStation 4 - the word is, Sony could unveil a new streaming service. Fans playing over the Internet will be able to play current PlayStation 3 titles on the new console, according to the Wall Street Journal, which cited unnamed sources who were in on the company's plans. In addition, according to WSJ, the new console would play new games stored on optical discs. Streaming games marks a first for video game consoles. From Gizmodo's Casey Chan: "It'll be interesting to see how Sony balances games on optical discs and games for streaming." Also rumored: The new device might be priced more competitively from the start compared with the PS3. Slash Gear, citing leaked internal documents obtained by a U.K. news outlet, suggests the PS4 could bow at $100 cheaper ($399) than the PS3 when it was introduced in 2006 ($499). That remains to be seen. Also remaining to be seen? A new controller. In a recent post, the Los Angeles Times" Salvador Rodriguez showed a photo that's hit the Web of what's rumored to be the new PlayStation 4 controller and its touch screen. Earlier this month, Hero Complex noted possible details of an upcoming PS4 console, along with the new website Sony launched where gamers can sign up to "be the first to know." The teaser video, above, is from that site. Amid the hoopla surrounding the upcoming announcement, Kotaku revived a story from 2012 about the device's rumored code name, Orbis, and how the numeral 4 isn't popular in Japan. It's "akin to the number 13 in the West," the blog writes. But there's a workaround, the blog notes: PlayStation "four" instead of "4."
