While much of the forecasting of the make-up of the 2019 grid has focused on Daniel Ricciardo's movements and whether Valtteri Bottas or Kimi Raikkonen can hold on at Mercedes and Ferrari respectively, could the real story be developing just behind them, with Fernando Alonso at McLaren?
Like Ricciardo, Bottas and Raikkonen, Alonso too is out of contract at the end of the year - a year in which he has added a full calendar in the World Endurance Championship to the intense globe-hopping of Formula 1.
The two-time world champion's passion for motorsport is clearly undimmed, for proof just look at his jubilant celebrations as he won the Six Hours of Spa-Francorchamps on his WEC debut recently.
It was particularly interesting, just five days later, to hear Alonso speak of his "sadness" at F1's modern-day predictability, in which McLaren remain firmly outside of the conversation for major honours at any weekend, despite their more powerful and more reliable power units.
Alonso's importance to McLaren is clear. Only title rivals Lewis Hamilton and Sebastian Vettel can match his record of scoring points in every race so far this year, while Stoffel Vandoorne's promise appears to be fading.
The Belgian has been beaten in qualifying and raceday at all five grands prix this year in what is already F1's most one-sided intra-team battle.
Team boss Zak Brown is a shrewd mover, indulging Alonso's 'Triple Crown' ambitions by letting him combine F1 duties with trips to the Indianapolis 500 and now a WEC season in which he will have two stabs at the Le Mans 24 Hours.
