It is also unclear whether Buxton is referring to an announcement in Formula 1 or perhaps in IndyCar. While the Brit does have a background in Formula 1 - about which he is currently co-hosts a podcast - his job is to cover IndyCar for the American network Fox.

In IndyCar, a key topic is the future of Scott Dixon, who is set to leave Chip Ganassi. He is expected to switch to the Arrow McLaren team. If Buxton is hinting at something in Formula 1, attention quickly turns to news surrounding Max Verstappen. The Dutchman is unhappy, with Red Bull’s RB22 unable to secure victories. Since Sunday, Verstappen can activate a clause that allows him to leave Red Bull Racing after this season.

It’s all speculation, of course, since Buxton offers no further hints. However, plenty of people are responding to his tweet and referencing Verstappen’s situation. Buxton’s followers expect that the anticipated announcement will indeed be about the former Formula 1 world champion.

Meanwhile, in GPblog's latest poll, readers have had their say on Verstappen's future with the Milton Keynes team. 63% of readers argue that Verstappen's 10-year stint at the Austrian team should come to an end, with only 37% believing the Dutchman should stay at a team he's been so loyal and successful with.

In the comments, however, there was a mixed view. One reader backed Red Bull and a team still full of talent (despite high-profile departures) to sort themselves out and give Verstappen a chance at winning once again, while another argued the Dutchman should indeed leave what was described as a "sinking ship."
