The game is never going to have widescreen. If it was a simple process then sure, but widescreen support has huge implications for the game as a whole, it's not just as simple as expanding the screen boundaries; it allows you to see far more of the screen than intended, which would reveal secrets hidden just off screen, require a huge change in enemy AI and behavior (unless you want enemies standing in full view and not doing anything), and many levels in the game would need to be redone entirely as they're not large enough to fill a widescreen space.
