Instead of just releasing an HD version of ICO on the PS Vita, Sony Worldwide Studio head Shuhei Yoshida had something different in mind. In the image you see above, a PS Vita is running ICO HD through the Vita’s remote play function, a function that allows you to control your PS3 from your handheld Vita similar to the Wii U gamepad. The above image was tweeted from Yoshida from his twitter.
While nothing is complete yet, he does comment that he has been testing the title, and that a patch is almost ready. When almost is would be completely up to your individual speculation.
