The PlayStation Vita enjoyed quite the showing on Sony's stage at the Tokyo Game Show, and portable fans are excited.

With a Japanese launch date of December 17, a total of 26 titles available for launch, and 3G capability for those willing to spring for the extra bucks, the Vita is lookin' good. However, there are few details that consumers will want to know, and those can be found by checking out this SCEI press release .

You will note a full list of peripherals and accessories that will be available at the Vita release. Optional items include a case, AC adapter, USB cable, cradle, portable charger, car adapter, and memory cards, which come in four sizes. As for the latter, you should also see a brief explanation found beneath the specs:

"Some PS Vita software titles may require the use of separately sold memory card for saving game’s saved data while some software titles are capable of saving it on to the PS Vita card itself. Please refer to the PS Vita game packages or game manuals for further details."

So that's interesting. Some games will call for a memory card, which doesn't come with the unit. Then there's the battery life information, which can be found in the same area. As you can see, the Vita will last 3-5 hours for playing games, around 5 hours for straight video, and 9 hours for listening to music with the Vita in standby mode. Charge time from a dead battery is about 2 hours and 40 minutes.

Well, that falls in line with the current PSP, doesn't it? I was using mine a lot when I didn't have power; it didn't last much longer than 3 hours when playing. But how do people feel about all this information?
