https://www.gtplanet.net/gran-turismo-sport-spec-ii-arrives-october-4/Like these titles, GT Sport Spec II will contain a whole raft of game updates on the disc — or in the download, if you prefer — to save on a lengthy update process. However there is no new game version to go with it; you'll simply get GT Sport complete up to the v1.39 update back in May. That means the new version will contain 275 of the game's 293 cars, and 75 circuits. For newcomers to GT Sport, or those wanting to install the game on a new console, it'll be something of a blessing.
The edition also includes 2.5 million in-game credits and 10 Gr.3 cars (check the site for the list).
Gran Turismo Sport's updates had reached a ridiculous size for a physical version, so this is great news. Shame it won't include the october update though, so everyone will still have to download the cars and tracks released from May until today.
