While it seems that the rumoured Dishonored sequel may skip this years E3, the franchise will still make the jump to new gen consoles in 2015.
A Definitive Edition of the original game has appeared on the Brazilian Ratings Board, and it is both submitted by publisher Bethesda, and slated for 2015. While no platform information is tied to to ratings application, it is probably safe to assume, that the Definitive Edition is on its way to PlayStation 4 and Xbox One.
As we wait for the heavily rumoured sequel, an updated version of the original does not sound too bad, because we quite liked it, when it was released back in 2012.
Thanks, IGN.
