Mike Hayes has confirmed that SEGA is planning on having 2 titles ready to release at Playstation Vita’s launch. One of the games is obviously the Virtua Tennis 4 port.
“On Vita, we can came out pretty early on and said we were going to give support to the hardware.
And we will have at least two titles at the launch of Vita. When exactly that’s going to be of course, we don’t know, but we’re assuming it’s going to be by the end of the Sony financial year, we guess, so we’ve got that.” – Mike Hayes, CEO of SEGA West
I would think it might be another port. I would not mind Valkyria Chronicles 3 for the West with trophies.
