The two broadcasters are sharing coverage of the sport from next season as part of a controversial deal which will see the satellite station show all 20 grands prix live, with the BBC showing 10 live and the other 10 in an as yet undetermined delayed format.
With Brundle by some distance the UKs highest-profile F1 pundit on the verge of moving to Sky for a sum believed to be in excess of £1 million per year BBC chiefs have a conundrum.
They can either go with the cheap option and use Skys commentary, which must be offered to them as part of the deal the two broadcasters cut and took to Formula One chief executive Bernie Ecclestone this summer, or they can continue to produce their own coverage.
If they opt for the first option it is unclear what it would mean for the rest of the BBCs production team. If they opt for the latter, believed to be more likely, it is understood that Speed TVs Australian commentator Leigh Diffey is the favourite to sit alongside present pundit David Coulthard.
Brundle, for his part, will be paired with David Croft in the Sky commentary booth the BBC Radio 5Live commentators colourful style is highly-rated by his new paymasters which will mean a return to the co-commentating duties he only recently vacated at the BBC.
His departure, which he has been mulling over for months, is a blow to the BBC, who had hoped the lure of speaking to millions on terrestrial TV would see him commit to a new deal.
Last Friday Brundle told his Twitter followers that he had had offers from both the BBC and Sky and would be taking the weekend to consider my future.
The 52 year-old former driver is believed to have been persuaded not only by the double-your-money offer from Sky but by the promise that he will be the star of its F1 coverage, heavily involved with much of the extra programming it is planning in an effort to convince fans to sign up to its subscription service.
Sky, which has been chasing Formula One for years, is desperate to make a big statement from the outset. Although its productions budgets, like the BBCs, have been trimmed, it still has a sizeable sum to spend on talent and programming.
The Daily Telegraph understands that Simon Lazenby, long-standing presenter of The Rugby Club, will likely present Skys coverage, while veteran sports presenter Steve Rider has been offered the chance to return in some capacity, possibly to front a feature looking at past drivers.
Sky is also understood to be keen on the BBCs pit-lane reporter Ted Kravitz who was seen in discussions with Sky executive producer Martin Turner in Singapore.
