The Sony boss didn’t have much else to say about the delay or the rationale behind it, but a Sony public relations representative did say COVID and remote work challenges are behind it. They promised a statement about the game soon and said:

It’s a situation Ryan said is unavoidable in the current climate, though he’s happy to wait and ensure the best version of the game releases.

The Gran Turismo series is certainly no stranger to delays. Gran Turismo 5 suffered continuous delays spanning several years between its announcement in 2005 and release in 2010. Here’s hoping Gran Turismo 7 won’t be subject to the same fate.

There are two approaches to this: you can either hold the date and put out the game irrespective of quality or you can ship it when it’s right. We have always taken the latter approach.
