German, Italian and Spanish product listings spotted by NeoGAF state the hardware pack will launch alongside the game in mid-November.

In addition to increased draw distances and higher resolution, the new-gen versions of the game will include denser traffic, a new foliage system, enhanced damage and weather effects, and more radio selections, with over 100 additional songs and DJ mixes.
Grand Theft Auto Online will support an increased player count, with online play for up to 30 players on PS4 and Xbox One. PS3 and Xbox 360 players will also be able to transfer their GTA Online characters and progression to their choice of the PS4, Xbox One or PC versions of the game.
According to an alleged leak, the digital PS4 version of GTAV will have a minimum install size of 50GB.
