If you watched Sony’s press conference, you would know that the Playstation Vita is the name of the next gen PSP. In the conference Sony showed off this montage trailer. If you fast forward it to 2:17, you will see a tennis game.
This looks just like Virtua Tennis franchise we all know and love. Its not out of the question for this type of game to be on a handheld. I think the arcade style of VT would do really well on the Playstation Vita and other portables. Shoot, SEGA agreed when back in 2005 the PSP got its own Virtua Tennis game called “Virtua Tennis: World Tour”.
I would say chances are good that this is a Playstation Vita Virtua Tennis games.
SEGA just sent out the press release for this. This is a port of Virtua Tennis 4 and is confirmed to be a launch title.
