Siri’s coming to Japan, but not to Apple TV. And, in a limited way, it may have made its way into the iPad, too.

Previous to the Apple event today, there had been speculation that an Apple iTV would be unveiled that reportedly would integrate Siri semantic-enabled voice technology into TV sets for viewers to use to speech-select their program choices. But the Apple TV accessory that was unveiled was, as noted here, an upgrade, not an overhaul, including support for video in 1080p.

Among the new iPad’s big features are its support for next-generation 4G LTE, HSPA+ and dual-channel HSDPA networks, and its retina display: 31 million pixels with resolution of 2048 by 1536 pixels. During the press conference Marketing chief Phil Schiller called it the best mobile display that ever shipped.

Less was made in the online coverage of the event of its inclusion of voice dictation, with a new built-in mike on the virtual keyboard. However, that may be coming courtesy of Siri. Over at 9to5Mac, a January story discussed the finding of an “About Dictation and Privacy” link in the keyboard menu for a beta of iOS 5.1 running on an iPad. When opened it provided the user with the standard legal literature and feature information for Siri Dictation, the report said, and considered that this might indicate that this will be an iPad 3 feature.

What iOS 5.1, which is available for download today, does for sure include is Siri in Japanese for iPhone 4S users. The big question is now, will it have to deal with the Siri brand issue for Japanese speakers that was first raised with the initial roll-out of the intelligent personal assistant? If you don’t recall, the talk then was that Siri in Japanese means buttocks.
