Naughty Dog's Game Director, Justin Richmond, has apparently confirmed that a Jak and Daxter HD collection for PS3 is in development, and will be releasing sometime in 2012.
"During an Uncharted 3-press conference in Oslo, Justin Richmond from Naughty Dog questioned about a lot of stuff, also the Jak and Daxter series. He clearly said too much when he told us that there will be a Jak and Dakter collection for Playstation 3 in 2012. This package will contain the first three games of the series and all will be upgraded in HD."
Naughty Dog's currently busy with Uncharted 3, which releases on November 1 in the US, and November 2 in the UK.
We'll get in touch with Sony, and see if they offer a comment.
