The Grand Tour Series 2?
As we keep seeing the question, here are some musings and a guesstimate
What we know
1) The Terrific Trio are contracted for 36 episodes over 3 years;
2) Series 1 started in November and consisted of 12 (counting Beach (Buggy) Boys as one programme) episodes;
3) The most highly regarded studio/tent segments, historically, of the Holy Trinity have been Christmas Gift Ideas. The most highly regarded films have been specials;
4) Given that the only way to watch the lads is an Amazon Prime subscription, Amazon, as a retailer, will probably be looking to capitalise from a larger membership base as the free, fast shipping is quite an incentive to use Amazon for other purchases. November-December-January is critical for a retailer.
It is fair to estimate, absent of any other information, that the second series will probably start sometime in November, run for 12 episodes and the interim will be used to film, edit and perfect the video segments which must be in place for the tent shooting, shoot the tent segments and put it all together.
This may be so wrong as to make all other wrong things look just a bit misguided but it's the best we mere mortals can estimate right now.
