I heard sometime late last year that there will be a new look or update to graphics when Fox League is launched. However that news might be old and might not happen and not sure if it’s just for Fox League or all the other channels will get it. The current look launched around the same time in 2015.
Otherwise it be branded:
500 - FS News 500
501 - Fox Sports 501
502 - Fox League
503 - Fox Sports 503
504 - Fox Footy
505 - Fox Sports 505
506 - Fox Sports 506
507 - Fox Sports Plus
I say the last of the Fox Sports 1-5 branding will be removed and instead use the channel numbers. Its only really Foxtel that still calls it Fox Sports 1, 2, 3, 4, 5
