Complete bullshit. Rockstar will not be releasing anything that can possibly eat into GTAV/GTA Online, especially with the next gen versions still not released.
Having said that, I would be overjoyed if this happened. It would be great to play these games with modern controls/graphics etc.
I hope they devote resources elsewhere instead of these. Unless they bring the aiming mechanics up to modern standards these would be a chore to play through again.
God I hope so. I've been asking for this for years. Countless hours playing those games and I'm hoping they spent the money to get most of the music rights. Small bump in graphics, just close to most of those mods they had taken down and smooth out the frame rates. I'm already sold.
