Overnight changes
Channel Update slates being prepared for channels 587, 588, 589, 590 & 591.
Those channel numbers don't mean a lot in isolation but deduct the number 60 from them and they bear a remarkable resemblance to the TNT Sports channel numbers!!!
Also a couple of promotional rebrands.
For full details of these and other changes see:

Although, perhaps not
full details of the 587-591 channel numbers as there is no speculation on the blog.
