Is there an official GTA 6 PS5 bundle?

Sony hasn't announced one. Its GTA 6 posts on the PlayStation Blog cover the limited-edition DualSense controllers and the pre-download, not a console bundle. Some retailers sell their own packages of a PS5 and a GTA 6 download code, such as Otto in Germany and EE in the UK, but those are a console and the game sold together by the shop.
