The PlayStation Vita is the most recent handheld console by Sony Computer Entertainment, and the successor to the PlayStation Portable, released in the end of 2011 and start of 2012. It's larger than a PlayStation Portable, with a wider screen to accompany the size increase. It offers 4-Core processing, an OLED touchscreen, Sixaxis motion sensing system, front and rear in-built cameras, and two analog sticks. There is also a PS Vita version supporting 3G connectivity and in-built GPS receiver.
The PS Vita is backwards compatible with all PlayStation Portable software, but like the PSP Go, it's not able to read UMD, relying on PlayStation Vita cards, a proprietary flash memory card. PlayStation Portable games and PlayStation Network and PlayStation Mobile software must be stored in PlayStation Vita memory cards.
On September 9th, 2013, Sony Computer Entertainment Japan announced the PlayStation Vita TV, a microconsole and a non-portable variant of the PlayStation Vita. At E3 2014, Sony Computer Entertainment America announced the localization of the Vita TV and it will be known in the western market as the PlayStation TV.
