I have reached out to a few contacts at TNT and WBD about the situation.
At present the UK league racing is very much up in the air with options being considered.
Do they use league Speedway as a cheap rights acquisition that’s UK based in the summer to help fill TNT schedule this will require an enhancement to production standards and costs on producing each meeting e.g More Cameras, better lighting, UHD coverage, new graphics etc
The other option is to remain as it is and look to cut some production costs bit further but then this will only be broadcast online via Discovery + which may upset fans and sponsors. It should all be decided in next few weeks once a few more things away from Speedway are sorted
