Rockstar officially announced the GTA 3/VC/SA remasters coming later this year. They also announced that they're about to remove the existing versions from stores, so if you want a version that's not tied to the rockstar launcher now's the time to grab them.
Apart from this what I'm curious is if they took the time to renew some of their music right. A bunch of songs got patched out over the years, so for many the Steam versions were already worse. Also of course what else they might add in these new versions, the press release says they're keeping the original look and feel. Hope they keep the cheats too.
