Sony Announces Entire Lineup for PlayStation VR 2 Release – Gaming – News

With regard to the GT7 news, as it is now in the article, the impression can be given that the VR mode will only consist of the online races.
In the PS blog this is described a bit differently:

We’re thrilled that Gran Turismo 7 will be a PS VR2 launch title! Through a free upgrade, for those who have already purchased Gran Turismo 7, players will experience all cars and tracks in VR like never before. GT7 in VR takes full advantage of PS VR2’s next gen features. With eye tracking and foveated rendering, players will experience stunning visual fidelity while racing in any of the 450+ cars. While 2-player splitscreen races are not supported in VR, all other races, including online races, will be available. From the Nürburgring to Tsukuba, tracks can be experienced exactly as they are in real life.

– Kazunori Yamauchi, President of Polyphony Digital

So it looks like the whole game except split screen. Good news!
