Had heard it was pretty much a done deal.
If needed, Honda has enough time to re-establish itself in the UK.It's a truly significant step for both companies, if that is the case.
But if I remember correctly, Honda no longer has an F1 division in the UK (they sold it off to Ross Brawn). Would it be feasible to work between the UK and Japan? At least with Mercedes, they were still located in the UK, so location wasn't a problem.
